About QTTG

Our group works on the frontier problems of transport of electron charge and spin in a variety of nanostructures. The research topics that we are currently pursuing include spintronics, carbon nanoelectronics,

topological insulators, thermoelectrics, and correlated heterostructures. 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 nonequilibrium Green function theory, density functional theory, and dynamical mean field theory.

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.
