Equivalence and superposition of real and imaginary quasiperiodicities
Xiaoming Cai, Shaojian Jiang
We take non-Hermitian Aubry-André-Harper models and quasiperiodic Kitaev chains as examples to demonstrate the equivalence and superposition of real and imaginary quasiperiodic pot…
Exact solutions of few-magnon problems in the spin- periodic XXZ chain
Ning Wu, Hosho Katsura, Sheng-Wen Li +2
We solve few-magnon problems for a finite-size spin- periodic Heisenberg XXZ chain with single-ion anisotropy through constructing sets of exact Bloch states achieving block dia…
Anderson localization and topological phase transitions in non-Hermitian Aubry-André-Harper models with p-wave pairing
Xiaoming Cai
We study non-Hermitian Aubry-André-Harper models with p-wave pairing, where the non-Hermiticity is introduced by on-site complex quasiperiodic potentials. By analysing the $\mathca…
Multi-particle quantum walks and Fisher information in one-dimensional lattices
Xiaoming Cai, Hongting Yang, Hai-Long Shi +3
Recent experiments on quantum walks (QWs) of a single and two particles demonstrated subtle quantum statistics-dependent walks in one-dimensional (1D) lattices. However the roles o…
