Professor Devereaux develops numerical methods and theories of photon-based spectroscopies of strongly correlated materials. The goal of his research is to understand electron dynamics via a combination of analytical theory and numerical simulations to provide insight into new quantum materials and how to better use them in applications that impact energy technologies. His group uses large-scale numerical simulations at local and Tier I computing facilities.

Brian is an Associate Staff Scientist at the SLAC National Accelerator Laboratory in the Stanford Institute for Materials and Energy Sciences (SIMES). Brian has used a variety of numerical techniques, including quantum Monte Carlo and exact diagonalization, to study model Hamiltonians of strongly correlated materials. Using efficient, parallel algorithms to perform numerical simulations, he is then able to compare his results to data from angle-resolved photoemission spectroscopy (ARPES) and resonant X-ray scattering. Recently, Brian has used a nonequilibrium formulation of dynamical mean-field theory (DMFT) to understand the behavior of correlated electron systems driven out of equilibrium by strong fields. He now focuses on understanding the nonequilibrium physics revealed by various types of pump-probe experiments including those performed using the soft x-ray (SXR) end-station at the Linac Coherent Light Source (LCLS).

Dr. Krzysztof Wohlfeld

I joined Tom Devereaux's group as a postdoc in November 2012 after staying as a Humboldt postdoctoral fellow in Jeroen van den Brink's group in IFW Dresden (Germany). I received my PhD in 2009 from the Jagiellonian University in Cracow (Poland) in the group of Andrzej M. Oles. My main research interests concerns understanding collective excitations in the transition metal oxides by developing simple but still rather realistic effective models, solving these models using combined analytic and simple numerical calculations, and then comparing the results to such experiments as resonant inelastic x-ray scattering (RIXS) or electron energy loss spectroscopy (EELS). This close collaboration between theory and experiment has recently allowed to identify an effective separation of spin and orbital degree of freedom of an electron in a quasi-1D cuprate (somewhat similarly to the well-known spin-charge separation in 1D interacting systems).

Graduate Student
  

Yvonne is a graduate student in physics at Stanford. She received an undergraduate degree in physics and a minor in biology from Stanford in 2009. Her interests lie in elucidating the behavior of strongly correlated systems using analytical and numerical techniques, such as determinant quantum Monte Carlo. These results can be compared to pump-probe experiments conducted at LCLS, as well as angle-resolved photoemission studies and x-ray absorption data. In the summer of 2012, she participated in the National Science Foundation’s East Asia and Pacific Summer Institutes program to study model Hamiltonians of strongly correlated materials using the tensor product state technique.

Graduate Student
  

Nachum has been a PhD student at Stanford since 2009. He has been conducting theoretical research in high temperature superconductors, focusing on interesting non-superconducting phases that may shed light on superconductivity. Using mean field theory, T matrix theory, and exact diagonalization, he studies proposed phases for the cuprates' pseudogap in both extended and 3-band Hubbard models, as well as the magnetic and orbital phases of iron-based superconductors and their impurity effects.
