Exact solutions of non-Hermitian chains with asymmetric long-range hopping under specific boundary conditions
Cui-Xian Guo, Shu Chen
We study one-dimensional general non-Hermitian models with asymmetric long-range hopping and explore to analytically solve the systems under some specific boundary conditions. Alth…
Exact zeros of the Loschmidt echo and quantum speed limit time for the dynamical quantum phase transition in finite-size systems
Bozhen Zhou, Yumeng Zeng, Shu Chen
We study exact zeros of Loschmidt echo and quantum speed limit time for dynamical quantum phase transition in finite size systems. Our results illustrate that exact zeros of Loschm…
Exact solution of single impurity problem in non-reciprocal lattices: impurity induced size-dependent non-Hermitian skin effect
Yanxia Liu, Yumeng Zeng, Linhu Li +1
Non-Hermitian non-reciprocal systems are known to be extremely sensitive to boundary conditions, exhibiting diverse localizing behaviors and spectrum structures when translational…
Dynamical evolution in a one-dimensional incommensurate lattice with symmetry
Zhihao Xu, Shu Chen
We investigate the dynamical evolution of a parity-time () symmetric extension of the Aubry-André (AA) model, which exhibits the coincidence of a localization-delocal…
Fate of zero modes in a finite Su-Schrieffer-Heeger Model with Symmetry
Zhihao Xu, Rong Zhang, Shu Chen +2
Due to the boundary coupling in a finite system, the zero modes of a standard Su-Schrieffer-Heeger (SSH) model may deviate from exact-zero energy. A recent experiment has shown tha…
Dynamical observation of mobility edges in one-dimensional incommensurate optical lattices
Zhihao Xu, Hongli Huangfu, Yunbo Zhang +1
We investigate the wave packet dynamics for a one-dimensional incommensurate optical lattice with a special on-site potential which exhibits the mobility edge in a compactly analyt…
