Abstract: We study non-Hermitian Aubry-André-Harper models with p-wave pairing, where the nonHermiticity is introduced by on-site complex quasiperiodic potentials. By analysing the PT symmetry breaking, winding numbers of energy spectra, localization and fractal dimensions of states,… read more here.
