Engineering mobility in quasiperiodic lattices with exact mobility edges
Zhenbo Wang, Yu Zhang, Li Wang +1
We investigate the effect of an additional modulation parameter on the mobility properties of quasiperiodic lattices described by a generalized Ganeshan-Pixley-Das Sarma model…
Anomalous second-order skin modes in Floquet non-Hermitian systems
Chun-Hui Liu, Haiping Hu, Shu Chen +1
The non-Hermitian skin effect under open boundary conditions is widely believed to originate from the intrinsic spectral topology under periodic boundary conditions. If the eigensp…
Accumulation of scale-free localized states induced by local non-Hermiticity
Cui-Xian Guo, Xueliang Wang, Haiping Hu +1
The bulk states of Hermitian systems are believed insensitive to local Hermitian impurities or perturbations except for a few impurity-induced bound states. Thus, it is important t…
Exact solution of the boundary-dissipated transverse field Ising model: Structure of Liouvillian spectrum and dynamical duality
Zhen-Yu Zheng, Xueliang Wang, Shu Chen
We study the boundary-dissipated transverse field Ising model described by a Lindblad Master equation and exactly solve its Liouvillian spectrum in the whole parameter space. By ma…
The simulation of non-Hermitian disordered system in linear circuits
Luhong Su, Hui Jiang, Zhan Wang +2
Non-Hermitian skin effect (NHSE) is a novel phenomenon appearing in non-Hermitian systems. Here, we report the experimental observation of NHSE. Different from the previous non-rec…
Dynamical singularity of the rate function for quench dynamics in finite-size quantum systems
Yumeng Zeng, Bozhen Zhou, Shu Chen
The dynamical quantum phase transition is characterized by the emergence of nonanalytic behaviors in the rate function, corresponding to the occurrence of exact zero points of the…
Engineering imaginary stark ladder in a dissipative lattice: passive symmetry, K symmetry and localized damping
Yu Zhang, Shu Chen
We study an imaginary stark ladder model and propose a realization of the model in a dissipative chain with linearly increasing site-dependent dissipation strength. Due to the exis…
Observation of critical phase transition in a generalized Aubry-André-Harper model on a superconducting quantum processor with tunable couplers
Hao Li, Yong-Yi Wang, Yun-Hao Shi +15
Quantum simulation enables study of many-body systems in non-equilibrium by mapping to a controllable quantum system, providing a new tool for computational intractable problems. H…
Localization, multifractality, and many-body localization in periodically kicked quasiperiodic lattices
Yu Zhang, Bozhen Zhou, Haiping Hu +1
We study the combined effect of quasiperiodic disorder, driven and interaction in the periodically kicked Aubry-André model. In the non-interacting limit, by analyzing the quasiene…
Exponential size scaling of the Liouvillian gap in boundary-dissipated systems with Anderson localization
Bozhen Zhou, Xueliang Wang, Shu Chen
We carry out a systematical study of the size scaling of Liouvillian gap in boundary-dissipated one-dimensional quasiperiodic and disorder systems. By treating the boundary-dissipa…
Symmetry and topological classification of Floquet non-Hermitian systems
Chun-Hui Liu, Haiping Hu, Shu Chen
Recent experimental advances in Floquet engineering and controlling dissipation in open systems have brought about unprecedented flexibility in tailoring novel phenomena without an…
