Abstract: The presence or absence of certain symmetries in the normal state (NS) also determines the symmetry of the Cooper pairs. Here, we show that parity ($\mathcal{P}$-) and time-reversal ($\mathcal{T}$-) odd Dirac insulators (trivial or topological)… read more here.

DOI: 10.1103/physrevb.102.224510
Abstract: Two dimensional topological superconductors (TS) host chiral Majorana modes (MMs) localized at the boundaries. In this work, within quasiclassical approximation we study the effect of disorder on the localization length of MMs in two dimensional… read more here.

DOI: 10.1103/physrevb.96.184516
Abstract: The bulk-boundary correspondence establishes a connection between the bulk topological index of an insulator or superconductor, and the number of topologically protected edge bands or states. For topological superconductors in two dimensions, the first Chern… read more here.

DOI: 10.1103/physrevb.98.220509
Abstract: Time-quasiperiodic Majoranas are generalizations of Floquet Majoranas in time-quasiperiodic superconducting systems. We show that in a system driven at d mutually irrational frequencies, there are up to 2^d types of such Majoranas, coexisting despite spatial… read more here.
