Excitation transfer in disordered spin chains with long-range exchange interactions
Nikolaos E. Palaiodimopoulos, Maximilian Kiefer-Emmanouilidis, Gershon Kurizki +1
We examine spin excitation or polarization transfer via long-range interacting spin chains with diagonal and off-diagonal disorder. To this end, we determine the mean localization…

Topological edge-states of the PT-symmetric Su-Schrieffer-Heeger model: An effective two-state description
A. F. Tzortzakakis, A. Katsaris, N. E. Palaiodimopoulos +4
We consider the non-Hermitian, parity-time (PT) symmetric extensions of the one-dimensional Su-Schrieffer-Heeger (SSH) model in the topological non-trivial configuration. We study…
