DESCRIPTION:Prof. Vojtech Vlcek (U. of California\, Santa Barbara)\nCaptur
 ing the dynamics of electronic excitations in realistic systems containing
  more than a few electrons is one of the outstanding theoretical challenge
 s. Dynamical quantum fluctuations mediate interactions among excited elect
 rons (and holes)\, determining the material electronic structure and optoe
 lectronic response. A predictive ab-initio theory is critical for understa
 nding\, predicting\, and designing novel compounds with tailored (quantum)
  properties. In this talk\, I will discuss my group's developments tacklin
 g the first-principles description of excitation dynamics in molecular and
  condensed systems containing up to several thousands of electrons. We emp
 loy the concept of downfolding - ``lossless'' compression of the (otherwis
 e intractable) many-body problem on an effective few-body problem solved b
 y a combination of real-time evolution of quantum fluctuations and statist
 ical correlators. I will exemplify these approaches in practical applicati
 ons to molecules and quantum materials. Together with efficient low-scali
 ng numerical techniques\, it is generally applicable to (quantum) material
  science and chemistry problems and constitutes an ideal platform for simu
 lating complex nanoscale systems\, such as molecular assemblies or materia
 ls interfaces. \n\nAbout the speaker:\nDr. Vlcek received his PhD in 2016
  jointly from The Hebrew University of Jerusalem (Israel) and University o
 f Bayreuth (Germany)\, where he studied in chemistry and physics departmen
 ts. His PhD was sponsored by Minerva Fellowship of the Max Planck society.
   From 2016 till 2018\, Dr. Vlcek continued as a postdoctoral researcher 
 at UCLA in the department of Chemistry and Biochemistry. He joined the fac
 ulty at UCSB in 2018. Our group focuses on development of new theoretical 
 approaches to electronic structure and dynamics. We combine density functi
 onal theory\, quantum field theory and quantum statistical methods with ra
 dically new stochastic approaches to investigate large systems where inter
 esting chemistry and physics occurs. In particular\, we are interested in 
 electronic excitations in chemically heterogeneous and complex nanoscale s
 ystems.
