Exact non-Hermitian mobility edges in one-dimensional quasicrystal lattice with exponentially decaying hopping and its dual lattice
Yanxia Liu, Yongjian Wang, Zuohuan Zheng +1
We analytically determine the non-Hermitian mobility edges of a one-dimensional quasiperiodic lattice model with exponential decaying hopping and complex potentials as well as its…
Information constraint in open quantum systems
Chun-Hui Liu, Shu Chen
We propose an effect called information constraint which is characterized by the existence of different decay rates of signal strengths propagating along opposite directions. It is…
Exact mobility edges, -symmetry breaking and skin effect in one-dimensional non-Hermitian quasicrystals
Yanxia Liu, Yucheng Wang, Xiong-Jun Liu +2
We propose a general analytic method to study the localization transition in one-dimensional quasicrystals with parity-time () symmetry, described by complex quasiper…
Localization transition, spectrum structure and winding numbers for one-dimensional non-Hermitian quasicrystals
Yanxia Liu, Qi Zhou, Shu Chen
By analyzing the Lyapunov exponent (LE), we develop a rigorous, fundamental scheme for the study of general non-Hermitian quasicrystals with both complex phase factor and non-recip…
Nonlocal effects of low-energy excitations in quantum-spin-liquid candidate CuZn(OH)FBr
Yuan Wei, Xiaoyan Ma, Zili Feng +8
We systematically study the low-temperature specific heats for the two-dimensional kagome antiferromagnet, CuZn(OH)FBr. The specific heat exhibits a dependence…
Graded Off-diagonal Bethe ansatz solution of the spin chain model with generic integrable boundaries
Xiaotian Xu, Junpeng Cao, Yi Qiao +3
The graded off-diagonal Bethe ansatz method is proposed to study supersymmetric quantum integrable models (i.e., quantum integrable models associated with superalgebras). As an exa…
Helical damping and anomalous critical non-Hermitian skin effect
Chun-Hui Liu, Kai Zhang, Zhesen Yang +1
Non-Hermitian skin effect and critical skin effect are unique features of non-Hermitian systems. In this Letter, we study an open system with its dynamics of single-particle correl…
One dimensional quasiperiodic mosaic lattice with exact mobility edges
Yucheng Wang, Xu Xia, Long Zhang +5
The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Interaction induced dynamical symmetry breaking in dissipative Fermi-Hubbard models
Lei Pan, Xueliang Wang, Xiaoling Cui +1
We investigate the dynamical properties of one-dimensional dissipative Fermi-Hubbard models, which are described by the Lindblad master equations with site-dependent jump operators…
Exact ground state and elementary excitations of a topological spin chain
Yi Qiao, Pei Sun, Junpeng Cao +3
A novel Bethe Ansatz scheme is proposed to calculate physical properties of quantum integrable systems without symmetry. As an example, the anti-periodic XXZ spin chain, a t…
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…
Topological Bose-Mott insulators in one-dimensional non-Hermitian superlattices
Zhihao Xu, Shu Chen
We study the topological properties of Bose-Mott insulators in one-dimensional non-Hermitian superlattices, which may serve as effective Hamiltonians for cold atomic optical system…
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…
