DOI: 10.1016/j.elspec.2016.10.003
Abstract: Abstract SnTe is a prototypical topological crystalline insulator, in which the gapless surface state is protected by a crystal symmetry. The hallmark of the topological properties in SnTe is the Dirac cones projected to the… read more here.

Abstract: We study the characterization of the non-Hermitian skin effect (NHSE) in non-Hermitian systems with on-site disorder. We extend the application of generalized-Brillouin-zone (GBZ) theory to these systems. By proposing a modified GBZ theory, we give… read more here.

DOI: 10.1103/physrevb.95.094512
Abstract: Berry connection is conventionally defined as a static gauge field in the Brillouin zone. Here, the authors show that for three-dimensional (3D) time-reversal invariant superconductors, a generalized Berry gauge field behaves as a fluctuating field… read more here.
