Topological signatures in the quench dynamics of periodically driven quantum systems
Ashutosh Dubey, Hironmoy Pratihar, Diptiman Sen +1
We study the quench dynamics of graphene, without and with a staggered mass, following the sudden switch-on of circularly polarized light where coupling to a fermionic bath is also…

Channel-selective magnetic filtering in a nodal-line semimetal
Hironmoy Pratihar, Alessandro De Martino, Arijit Kundu
We study quantum transport through a magnetic barrier in a nodal-line semimetal. When the Fermi energy lies near the nodal ring, the Fermi surface has toroidal geometry. Each cross…
