Pseudo PT symmetric lattice

Published 13 Nov 2014 in quant-ph, math-ph, and math.MP | (1411.3459v1)

Abstract: We study pseudo PT symmetry for a tight binding lattice with a general form of the modulation. Using high-frequency Floquet method, we show that the critical non-Hermitian degree for the reality of the spectrum can be manipulated by varying the parameters of the modulation. We study the effect of periodical and quasi-periodical nature of the modulation on the pseudo PT symmetry.
