Volkov-Pankratov states on the edge of a quantum spin Hall system
Vivekananda Adak, Subhadeep Chakraborty, Krishanu Roychowdhury +1
Volkov-Pankratov (VP) states are a family of sub-gap states which appear at the smooth interface/domain wall between topologically distinct gapped states. We study the emergence of…

Supersymmetry on the lattice: Geometry, Topology, and Flat Bands
Krishanu Roychowdhury, Jan Attig, Simon Trebst +1
In quantum mechanics, supersymmetry (SUSY) posits an equivalence between two elementary degrees of freedom, bosons, and fermions defined by local rules. Here we apply it to find co…
