This implies that any theoretical study on DNA should take into consideration the vast variety of space and time scales, making it necessary the adoption of multi-physics approaches, covering the entire range of theoretical methods from quantum chemistry to rough mesoscopic models. Within this scenario the importance of data to bias simulations and as a reference to calibrate low resolution methods (Dans et al. 2017; Neguembor et al. 2022; Schultz et al. 2025).<br>\r\nLarge efforts have been made to develop accurate low level DFT and semiempirical methods that can be data-providers for a new generation of force-field, as well as integrated in QM/MM packages for an efficient representation of DNA reactivity (Aranda et al. 2019). Atomistic force-field have gained accuracy, showing good ability to reproduce unusual forms of DNA and long segments of DNA in the context of chromatin (Collepardo-Guevara et al. 2015; Genna et al. 2025) and providing very useful data for the calibration of lower level coarse-grained or mesoscopic methods(De Pablo 2011; Farré-Gil et al. 2024) ,which have gained sequence specificity, scalability and computational efficiency, allowing to simulate kilo-to-megabase fragments of DNA. Very remarkable efforts have been made to move up these methods to represent chromatin, which requires the introduction of biases derived from experimental data (MNAseq, chromosome conformation capture, and even static or dynamic pictures obtained by ultra-resolution microscopy, and others (Buitrago et al. 2019; Neguembor et al. 2022; Li and Schlick 2024)). This has opened the possibility to recover dynamic “base-pair” resolution pictures of chromatin and study aspects from local and global chromatin rearrangements to inter-play between effector proteins and nucleosomes, the impact of lesions in chromatin structure, and even the role of phase separation in defining local chromatin arrangements (Joseph et al. 2021; Liu et al. 2025; Park et al. 2025).<br>\r\nAs the target systems move from the small atomistic detail to the entire chromatin fiber, the community is broken into different sub-communities. This generates a risk of disconnection, which would lead to a waste of effort reformulating solutions to already solved problems, or ignoring the characteristic that a method should have to maintain coherence with more accurate models, or to scale to represent systems of real biological interest. This will be the main objective of this meeting, which will join a variety of sub-communities with a common interest: the DNA.<br>\r\n<br>\r\n<strong>References</strong><br>\r\n<br>\r\n<a href=\"https://doi.org/10.1038/s41929-019-0290-y\" target=\"_blank\">[1] J.

Modern light sources allow the probing of equilibrium and non-equilibrium phenomena with Å‐level spatial resolution and femto‐ to attosecond temporal precision. Advances in ultrafast laser technology, together with the rise of X-ray free‐electron lasers and next-generation synchrotron sources, have repeatedly pushed the boundaries of spectroscopic methods from low‐frequency collective modes in biomolecules to electronic and core‐level dynamics. An extensive toolbox of linear and multidimensional spectroscopic techniques now spans the entire electromagnetic spectrum. Terahertz (THz) pulses can coherently drive intermolecular and lattice vibrations in solids and soft matter [1], Mid‐IR and Raman methods map vibrational energy (re)distribution in liquids and vibrational signatures of individual modes in complex molecules [2]. Visible spectroscopy tracks ultrafast charge dynamics in chromophores [3] and photochemical molecular pathways [4], while X-ray sources from free-electron lasers and high-harmonic generation setups enabled time-resolved X-ray diffraction of gas‐phase [5] and condensed systems [6].<br>\r\nDespite sharing common scientific goals, the respective communities have traditionally operated in relative disconnection from each other, relying on different approximations, targeting different observables, and employing distinct numerical implementations. This disconnection manifests, among other symptoms, in the fact that schools, conferences, and workshops are often dedicated to a specific frequency window (e.g. IR spectroscopy) or to simulation methods targeting a class of specific processes (e.g. vibrational dynamics). Opportunities for dialogue and the building of a shared language are lacking. In fact, while preparing this proposal, it became evident that even foundational terms like ab initio or quantum dynamics carry different meanings across communities.<br>\r\nTo address this fragmentation, the proposed CECAM school brings together researchers from diverse backgrounds to foster mutual understanding and build lasting conceptual bridges. Over five days, participants will engage with both the theoretical foundations and practical implementations of spectroscopies across different communities. We will highlight the fact that despite their apparent differences, all spectroscopic methods can be traced back to a common starting point: a light–matter Hamiltonian that includes the quantum description of electronic, nuclear, and photonic degrees of freedom. From this unified framework, we will explore how different approximations—introduced at various stages—lead to the distinct theoretical approaches adopted in each field.<br>\r\nThe first part of the school will focus on approaches that solve the exact quantum molecular dynamics in reduced dimensionality. Within this framework, molecules are treated fully quantum-mechanically, while light is treated classically as an external perturbation within the dipole approximation. From the matter perspective, this means that the full electron + nuclear wavefunction is accessible, offering a great level of detail and information, and the accurate treatment of non-Born-Oppenheimer dynamics. From the light perspective, this means that spectroscopic signals are conveniently calculated via the response function approach (RFA) [7], which is however only valid in the weak field limit. Recently, the RFA has been used to design and simulate several spectroscopic signals of femtosecond molecular photochemistry using novel X-ray pulse sources [8], including stimulated X-ray Raman [9], transient X-ray absorption and transmission [10], and many others [11].<br>\r\nIn the second part, we will shift the focus to longer time scales with more degrees of freedom and study larger molecules in explicit environments (solvent, substrate, etc). In these cases, it is common practice to apply the Born-Oppenheimer approximation and take the classical limit for the nuclei, while keeping the electrons quantum, leading to (finite temperature) molecular dynamics (MD) approaches. To make these simulations computationally tractable, while retaining an explicit description of the electrons, electron–electron interactions are typically simplified using ground-state density functional theory (DFT). This approach, commonly referred to as ab initio molecular dynamics (AIMD), enables the simulation of vibrational spectroscopies such as infrared (IR) and Raman [12,13], as well as surface-specific techniques like sum-frequency generation (SFG) [14,15]. To access larger system sizes and longer simulation timescales, forces can be derived from classical interatomic potentials, facilitating the convergence of multidimensional spectroscopic observables such as THz-Raman spectra [16]. Alternatively, forces can be learned directly from first-principles data using machine-learning (ML) models, enabling ML-driven molecular dynamics and spectroscopy [17-21]. Through path integral techniques, the quantum nature of the nuclei can be recovered, which is particularly important for systems containing light atoms, such as hydrogen [22-24].<br>\r\nThe third part of the school will explore what happens when the primary interest shifts from vibrational to electronic dynamics. In this context, the electron dynamics at the DFT level can be incorporated by considering its time-dependent version (TDDFT), where the exchange-correlation functionals are usually adiabatic. With this method, UV-visible absorption [25], circular dichroism [26], inelastic X-ray scattering, and electron energy loss [27], and other spectroscopies can be computed. Finally, there are situations in which strong light-matter coupling demands an explicit treatment of the photons [28]. These can be reintroduced either by dressing the Kohn-Sham Hamiltonian with electron-photon exchange-correlation potentials (known as quantum-electrodynamics DFT, or QEDFT) [29] or by a semiclassical treatment of the photons solving Maxwell’s equations (the Maxwell-TDDFT method)[30]. These methods enable the calculation of spectra in cavities or arbitrary electromagnetic environments [31], and can account for polaritonic phenomena, radiative lifetimes, superradiance, and many more.<br>\r\nThis school brings together leading experts from exact quantum dynamics, ab initio MD, ML‐enabled simulations, and Maxwell–TDDFT to forge a common language and cross‐fertilize ideas. Lectures will cover both the fundamental principles and the latest advances in each area, highlighting current applications and open challenges. Complementing the lectures, hands-on tutorials will reinforce foundational concepts and provide important hands-on experience on several popular computational approaches (see hands-on section below).<br>\r\nBy spanning the electromagnetic spectrum and the hierarchy of theoretical methods, this school will equip PhD students and postdocs with a unified, multi‐scale, and inter-community perspective on quantum dynamics and spectroscopy. Participants will leave with both a solid grounding in foundational techniques and direct experience of the latest computational frontiers, ready to tackle open challenges in molecular and materials science.<br>\r\n<br>\r\n<strong>References</strong><br>\r\n<br>\r\n<a href=\"https://doi.org/10.1063/1.4901216\" target=\"_blank\">[1] P.

This is evident from the now-standard use of molecular dynamics simulations by molecular biologists and biophysicists, and the remarkable success of AlphaFold, which has convinced even the most skeptical of the critical role of these methods in contemporary biological research.<br>\r\nHowever, new challenges are emerging. It is increasingly apparent that to understand biomolecular function, we must move beyond studying isolated molecules. The focus is now shifting towards examining large, dynamic complexes of biomolecules within their complex native environments, complete with post-translational modifications. Embracing this complexity is crucial for understanding how biological functions and cellular structures emerge and adapt.<br>\r\nThis workshop will address existing and emerging frontiers, discussing both current challenges and the future of molecular simulations needed to meet them. It will gather simulation experts that have been actively developing methods that can increase simulation accuracy and extend their applicability range across multiple scales, as well as experimentalists performing advanced studies that can address outstanding challenges occurring at computationally accessible time and length scales. A main aim will be to discuss how to improve the accuracy of simulations, integrate simulations and cutting-edge experiments, and how to best take advantage of innovative enhanced sampling and machine learning-based approaches.<br>\r\nThe workshop will seize the opportunity to celebrate the outstanding scientific achievements of Gerhard Hummer, a prominent leader in the field, on his sixty’s birthday. Many of the participants that have already expressed their intention to attend and support the workshop or past or current theoretical and experimental scientist that have been either collaborators and co-authors, mentored by, or inspired by Gerhard’s ideas and expertise.</p>", "image_description": "", "creation_date": "2026-01-26T15:39:35", "last_modification_date": "2026-01-26T16:44:37", "link_label": "Bridging Biomolecular Simulations and Experiments Across Time and Length Scales: from Single Molecul", "link_url": "https://www.cecam.org/workshop-details/bridging-biomolecular-simulations-and-experiments-across-time-and-length-scales-from-single-molecules-to-entire-organelles-1493", "canceled": "False", "cancel_reason": "", "place_and_room": "BCH 2103", "url_place_and_room": "https://plan.epfl.ch/?room==BCH%202103", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "", "organizer": "<strong>Nicolae-Viorel Buchete</strong>, University College Dublin ; <strong>Pilar Cossio</strong>, Flatiron Institute ; <strong>Roberto Covino</strong>, Goethe University Frankfurt -- Frankfurt Institute for Advanced Studies ; <strong>Ville Kaila</strong>, Stockholm University ; <strong>Edina Rosta</strong>, University College London", "contact": "<a href=\"mailto:[email protected]\"><strong>Cornelia Bujenita</strong></a>, CECAM Events and Operations Manager", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 1, "fr_label": "Sur inscription", "en_label": "Registration required" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/119449/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api", "https://memento.epfl.ch/api/v1/mementos/8/?format=api" ] }, { "id": 71443, "title": "Mathematics Colloquium", "slug": "mathematics-colloquium-13", "event_url": "https://memento.epfl.ch/event/mathematics-colloquium-13", "visual_url": "https://memento.epfl.ch/image/32790/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32790/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32790/max-size.jpg", "lang": "en", "start_date": "2026-06-17", "end_date": "2026-06-17", "start_time": "16:15:00", "end_time": "17:15:00", "description": "<strong>Title</strong>: <br>\r\nPositive random walks and positive-semidefinite random matrices<br>\r\n<br>\r\n<strong>Abstract</strong>:<br>\r\nOn the real line, a random walk that can only move in the positive direction is very unlikely to remain close to its origin. After a fixed number of steps, the left tail has a Gaussian profile under minimal assumptions. Remarkably, a similar phenomenon occurs when we consider a positive random walk on the cone of positive-semidefinite matrices. After a fixed number of steps, the minimum eigenvalue is described by a Gaussian random matrix model.<br>\r\nThis talk introduces a new way to make this intuition rigorous.

Local access to specific genomic regions is facilitated by repositioning nucleosomes to enable transcription and other nuclear processes. Nucleosome positioning is primarily regulated by ATP-dependent chromatin remodeling enzymes (CRs) that belong to the Snf2-type helicase family. These enzymes disrupt histone-DNA contacts by consuming ATP. The functions of CRs can be redundant or essential, complicating their study in vivo. To address this, we employ a unique bottom-up approach, in which we reconstitute chromatin in vitro using purified proteins and a yeast genomic plasmid library. To elucidate the diverse remodeling functions of CRs, we add purified CRs in combination with various transcription factors to the in vitro reconstituted chromatin. The resulting changes in nucleosome positioning are monitored using MNase-seq. Depending on the type of CR used, we observe distinct nucleosome positioning patterns. Furthermore, we have expanded our in vitro reconstitution approach to explore the 3D genome organization of reconstituted chromatin, discovering a role for CRs in the 3D genome organization of <em>S. cerevisiae</em>.</p>", "image_description": "", "creation_date": "2026-01-23T09:41:37", "last_modification_date": "2026-03-10T12:18:20", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "BCH 2218", "url_place_and_room": "https://plan.epfl.ch/?room==BCH%202218", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<a href=\"https://www.uni-goettingen.de/en/689675.html\">Elisa Oberbeckmann</a> (University of Goettingen)", "organizer": "Professeur Beat Fierz", "contact": "Marie Munoz", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 3, "fr_label": "Entrée libre", "en_label": "Free" }, "keywords": "CBseminar", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/119413/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/1/?format=api", "https://memento.epfl.ch/api/v1/mementos/14/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api" ] }, { "id": 70936, "title": "Probing and Modulating Transcription Factor–DNA Interactions via Chemically Modified Proteins", "slug": "probing-and-modulating-transcription-factordna-i-2", "event_url": "https://memento.epfl.ch/event/probing-and-modulating-transcription-factordna-i-2", "visual_url": "https://memento.epfl.ch/image/32324/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32324/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32324/max-size.jpg", "lang": "en", "start_date": "2026-05-19", "end_date": "2026-05-19", "start_time": "16:15:00", "end_time": "17:45:00", "description": "<p>Chemical protein synthesis provides a powerful means to prepare novel, modified proteins with atomic-level precision, offering unprecedented opportunities to understand fundamental biological processes.<sup>1</sup> Of particular interest is gene expression, which is controlled through interactions between transcription factors (TFs) and DNA.

Specific examples will focus on the synthesis of site-specifically phosphorylated and acetylated TFs, such as the Myc/Max system.<sup>2, 3</sup> Remarkably, these studies revealed that phosphorylation and acetylation patterns modulate Max–DNA interactions by altering DNA binding affinity and sequence specificity. Importantly, such mechanistic insights led to the development of novel bioactive miniproteins derived from Max (μMax), capable of inhibiting oncogene expression and cancer cell proliferation through antagonistic binding to target genes in cancer cells, paving the way for the development of new therapeutic proteins targeting oncogene expression.<sup>4-6</sup><br>\r\n<br>\r\n<br>\r\n1.

Practical applications of hBN spin centres as<br>\r\nintrinsic magnetic field, temperature, pressure, etc. sensors in van der Waals heterostructures are hence<br>\r\nenvisioned. To further boost the quantum sensing applications of this spin defect in hBN, we are currently<br>\r\ninvestigating the dynamics of the intermediate state, also known as the metastable state, because it is likely<br>\r\nto trap electrons for a certain time, which affects the subsequent sensing protocol when the pulsed<br>\r\nmagnetic resonance experiment is designed.</p>", "image_description": "Prof. Vladimir Dyakonov", "creation_date": "2026-04-01T09:02:57", "last_modification_date": "2026-04-01T10:43:24", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "BM 5202", "url_place_and_room": "https://plan.epfl.ch/?room==BM%205202", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<strong>Prof. Vladimir Dyakonov</strong> holds the Chair of Experimental Physics on the Faculty of Physics and Astronomy of Julius-Maximilian University of Würzburg, Germany since 2004.
