Thomas P. Devereaux

Thomas P. Devereaux

Professor Devereaux is the Director of the Stanford Institute for Materials and Energy Sciences (SIMES, the Materials Science Division at SLAC), a professor in the Photon Science Faculty at SLAC and Stanford University, and a Senior Fellow of the Precourt Institute for Energy. His main research interests lie in the areas of theoretical condensed matter physics and computational physics. His research efforts focus on using the tools of computational physics to understand quantum materials and how spectroscopies can be used to fingerprint the influence of multiple degrees of freedom, interactions, and phases that lead to technologically relevant materials properties.

"As the speed and cost of computing continues to improve, we are poised to tackle heretofore unaddressed problems, with the goal of understanding electron dynamics via a combination of analytical theory and numerical simulations to provide insight into materials of relevance to energy science."

John J. Rehr

John J. Rehr

Professor Rehr is an Emeritus Professor of Physics at the University of Washington, and Adjunct Faculty of Photon Science at SLAC. Professor Rehr is the Principal Investigator of the FEFF Project and leads the Theoretical X-ray Beamline of the European Theoretical Spectroscopy Facility (ETSF). Professor Rehr's research specialties are in condensed matter theory, with major interests in excited state electronic structure and the theory of x-ray and electron spectra. His group is well known for developing quantitative theories and ab initio codes for x-ray and electron-spectroscopies, as implemented, for example, in the FEFF codes.

Joel E. Moore

Joel E. Moore

Professor Moore is a Professor of Physics at the University of California, Berkeley, and Joint Faculty Scientist in the Materials Sciences Division at the Lawrence Berkeley National Laboratory (LBNL). Professor Moore's research seeks to understand how applying the rules of quantum mechanics to systems of many interacting particles leads to a remarkable variety of emergent phenomena. Some of these phenomena we study because of their potential relevance to real-world problems, including information technology and alternative energy, and some we study simply in order to understand the physical world. His current interests include topological phases, spin and heat transport, and non-equilibrium coherent dynamics as measured in ultrafast optical experiments.

Brian Moritz

Brian Moritz

Brian is a Staff Scientist at SLAC in the Stanford Institute for Materials and Energy Sciences (SIMES). Brian uses a variety of numerical techniques, including quantum Monte Carlo and exact diagonalization, to study models for strongly correlated materials. Using efficient, parallel algorithms to perform numerical simulations, results can be compared to data from angle-resolved photoemission spectroscopy (ARPES) and other X-ray spectroscopies (primarily XAS, XES, and RIXS). His recent focus includes understanding the nonequilibrium physics revealed by various types of pump-probe experiments, including those performed at the Linac Coherent Light Source (LCLS).

Sri Chaitanya Das Pemmaraju

Das is an Associate Staff Scientist at SLAC jointly appointed between TIMES, SSRL and LCLS. His research focuses on using ab initio methods to simulate X-ray spectroscopies in materials and molecular systems, particularly for systems driven out of equilibrium for which he currently is developing real-time TDDFT codes.

Josh Kas

Josh Kas

Josh is an Acting Assistant Professor and member of the FEFF Project team at the University of Washington. His interests include the development of FEFF and extensions to calculate near-edge XAS spectra (XANES), modeling and incorporating self-energy effects into FEFF, and ab initio evaluation of RIXS spectra.
