Wave functions describing bound states of electronic systems satisfy high-dimensional Schrödinger equations whose potentials exhibit Coulomb singularities at particle-collision configurations. These singularities generate cusps that limit the global regularity of the wave function in spectral Barron spaces, which are particularly relevant to the analysis of Fourier-based approximation methods and neural networks.
\r\nIn this talk, we study the effect of extracting a truncated Jastrow factor designed to capture the leading coalescence singularities while preserving the asymptotic behavior of the wave function at infinity. We show that the resulting quotient gains one full order of spectral Barron regularity: whereas the original wave function typically belongs to spaces of order (s<1), the Jastrow quotient belongs to those of order (s<2). An explicit hydrogenic example shows that the threshold (s=2) is natural.
\r\nThe proof relies on conjugating the Hamiltonian by the Jastrow factor and carrying out a global Fourier-space analysis. It combines resolvent estimates, precise control of singular coefficients, and a fixed-point argument separating low and high frequencies.

\r\nThe electronic structure reading group brings together researchers and students interested in mathematical aspects of electronic structure problems and adjacent topics, including:\r\n
During this afternoon, you will work on hands-on exercises in Fiji for everyday tasks such as building your own macros, opening large datasets and image display tricks. More advanced topics, such as how to perform curve fitting, plotting line profiles, reslicing your data and batch processing, are also included.
\r\n
\r\nPlease feel free to suggest extra topics when you register. Depending on the replies, this will tailor the end of the day with some practicals ( for example : Colocalization, Tracking with Trackmate or cell detection with StarDist or Cellpose in Fiji ... )
\r\nWhile the course is of general use, the examples and applications are primarily relevant for those using light microscopy techniques.\r\n
In 2026, EPFL named Professor Konstantin Novoselov its first-ever EPFL Fellow, a newly created honorary title recognising scientific personalities of exceptional international stature.
\r\n
\r\nEPFL is delighted to host a public lecture to celebrate this nomination of one of the most influential physicists of our time.
\r\n
\r\nKonstantin Novoselov was awarded the Nobel Prize in Physics in 2010 and is globally renowned for his pioneering work on graphene and two-dimensional materials. By isolating graphene for the first time, a sheet of carbon just one atom thick, he opened an entirely new field of research, with profound implications for electronics, energy and quantum technologies.
\r\n
\r\nPicture this: it was from the graphite of an ordinary pencil lead that this \"super-material\" was first isolated. Using nothing more than a piece of adhesive tape to peel away a layer a single atom thick, Konstantin Novoselov revealed to the world a material with extraordinary properties. A million times thinner than a human hair, 200 times stronger than steel and remarkably conductive, graphene pushes every limit. From the lead of your pencil to the batteries of tomorrow, join us to discover how a deceptively simple gesture set off a genuine technological revolution.
\r\n
\r\nThis Campus Lecture offers an introduction to that revolution: how a two-dimensional material is transforming our understanding of matter and how today's fundamental discoveries become tomorrow's technologies.

\r\nAbout Konstantin Novoselov
\r\nKonstantin Novoselov is a physicist specialising in condensed matter and nanotechnology. He conducted his Nobel Prize–winning research at the University of Manchester, where, together with Professor Andre Geim, he isolated graphene for the first time. He has held academic positions in the United Kingdom as well as internationally and is currently based at the National University of Singapore. Widely recognised as a leading figure in the study and application of two-dimensional materials, he has received numerous honours for his contributions to science.
