WHAT WE DO
We develop and employ theoretical and computational methods such as first-principles Open Quantum Dynamics based on density-matrix formalism, Many-Body Perturbation Theory, and Density-Functional Theory, to understand and predict complex solid-state and nanostructures’ properties including spin-optronics, excited-state dynamics, spin and electron relaxation and transport at the atomistic levels, for quantum information science, microelectronics, and energy conversion applications.
Our research is currently funded by National Science Foundation (DMR/CMMT, CHE, Wisconsin MRSEC), Department of Energy – Basic Energy Science (Computational Chemical Science, Computational Materials Science, EFRC CHOISE), AFOSR (Young Investigator Program, CFIRE), MOORE Foundation, and SLOAN Fellowship.
OUR RESEARCH
Current research topics: a) electronic excitation including many-body interactions; b) spin relaxation in solids by density-matrix dynamics; c) solid-state spin defect properties.
