Non-Hermitian mobility edges in one-dimensional quasicrystals with parity-time symmetry

Yanxia Liu, Xiang-Ping Jiang, Junpeng Cao +1

We investigate localization-delocalization transition in one-dimensional non-Hermitian quasiperiodic lattices with exponential short-range hopping, which possess parity-time ($\mat…

Diagnosis of bulk phase diagram of non-reciprocal topological lattices by impurity modes

Yanxia Liu, Shu Chen

We study the single impurity problem in the non-Hermitian lattice described by the non-reciprocal Su-Schrieffer-Heeger model and obtain the phase diagram of localized bound states…

Mass-imbalanced atoms in a hard-wall trap: an exactly solvable model with emergent $D_{6}$ symmetry

Yanxia Liu, Fan Qi, Yunbo Zhang +1

We show that a system consisting of two interacting particles with mass ratio $3$ or $1/3$ in a hard-wall box can be exactly solved by using Bethe-type ansatz. The ansatz is based…
