About QTTG
|
Our group conducts research on the frontier problems of quantum transport of electron charge and spin in a variety of nanostructures. The research topics that we are currently pursuing include:
We are also working on the development of new theoretical and computational formalisms, often involving massively parallel codes, which are required to study quantum many-body systems far from equilibrium. The principal tools that we employ daily include [Fast facts about NEGF|nonequilibrium Green function theory], density functional theory, and dynamical mean field theory. Our research is supported by the National Science Foundation and the U.S. Department of Energy.

Research Highlights

The image on the left depicts bilayer-CrI3/monolayer-TaSe2 van der Waals heterostructure for which we predict current-pulse driven nonequilibrium phase transition where spin-orbit torque, generated by monolayer of metallic transition metal dichalcogenide TaSe2, switches insulating antiferromagnet bilayer-CrI3 into ferromagnet in reversible fashion and with those phases being stable in between two pulses.
