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…

Topological zero-reflection points in multi-terminal quantum wire junctions
Abhiram Soori, Udit Khanna, Diptiman Sen
We study scattering in noninteracting multi-terminal quantum wire junctions and show that junctions with dihedral symmetry can exhibit exact zero-reflection points for te…
