Condensed Matter Physics

My group 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 energy-related applications. His group carries out numerical simulations on high-performance CPU and GPU mid-range computing clusters and supercomputers. Currently, we are calculating a variety of photon-based spectroscopies in strongly correlated materials to understand emergent phases of matter and how states of matter evolve in the time-domain when pumped by lasers. We use Quantum Monte Carlo, exact diagonalizations, dynamical mean field theory, and non-equilibrium Green's function techniques and algorithms to in multi-scale computing applications. We work very closely with experimentalists using modern light sources, such as the Linac Coherent Light Source and the Stanford Synchrotron Radiation Lightsource. We are part of the Stanford Institute of Materials and Energy Science (SIMES) and are funded largely by the Department of Energy.
