Quantized Transport in Floquet Topological Insulators
Rekha Kumari, Manas Kulkarni, Abhishek Dhar
We study quantum transport in a periodically driven (Floquet) topological system coupled to static fermionic reservoirs. Using the Floquet nonequilibrium Green's-function (NEGF) fo…

Fermi-arcs mediated transport in surface Josephson junctions of Weyl semimetal
Rekha Kumari, Dibya Kanti Mukherjee, Arijit Kundu
This study presents Fermi-arcs mediated transport in a Weyl semimetal thin slab, interfacing two -wave superconductors. We present detailed study with both time-reversal and inv…

Valley filtering and valley valves in irradiated pristine graphene
Rekha Kumari, Gopal Dixit, Arijit Kundu
We theoretically study valley-filtering in pristine graphene irradiated by bicircular counter-rotating laser drive. The dynamical symmetry of the graphene and laser drive disrupts…
