WebIrreducible first Brillouin zone#. The first Brillouin zone as described above ignores the possibility of rotational symmetries. Such a definition of the Brillouin zone contains redundant information in the case of a system posessing a non-trivial Point group, and a smaller cell is the true Brillouin zone. WebIn the irreducible wedge of the Brillouin zone 3000 k-points are used for integration. During SCF calculations, the energy and charge are set to converge be 0.0001 Ry and 0.0001 e, respectively. To compute the transport coefficients, a large k-point mesh with 120 000 k-points were employed.

WebWe study the characterization of the non-Hermitian skin effect (NHSE) in non-Hermitian systems with on-site disorders. We extend the applications of generalized-Brillouin-zone (GBZ) theory to these systems. By proposing a modified GBZ theory, we give a faithful description of the NHSE.
