Emergent Kinetic Constraints and Subspace Fragmentation in Rydberg Arrays
Wen-Jie Geng, Zhenming Zhang, Wei Yi
In a strongly interacting Rydberg atom array, the dynamics are often constrained to the decoupled Hilbert subspaces, representing an intriguing paradigm for nonergodicity. By consi…
Topological Word for Non-Abelian Topological Insulators
Zhenming Zhang, Tianyu Li, Wei Yi
We propose a unified framework, dubbed topological word, for the complete non-Abelian bulk-boundary correspondence in multigap non-Abelian topological insulators. Composed by an or…
Anomalous localization and duality in non-Hermitian quasiperiodic models
Wenzhi Wang, Tianyu Li, Wei Yi
We develop a general framework based on the sign patterns of Lyapunov exponents for engineering and characterizing counterintuitive localization properties in one-dimensional non-H…
Family of self-dual quasicrystals with critical Phases
Wenzhi Wang, Wei Yi, Tianyu Li
We propose a general framework for constructing self-dual one-dimensional quasiperiodic lattice models with arbitrary-range hoppings and multifractal behaviors. Our framework gener…
Dynamic transition of the density-matrix topology under parity-time symmetry
Wenzhi Wang, Wei Yi
Density-matrix topology, defined through the geometric property of the relevant modular Hamiltonian, can undergo transitions in the corresponding open-system dynamics. While symmet…
Biorthogonal topological charge pumping in non-Hermitian systems
Zhenming Zhang, Tianyu Li, Xiwang Luo +1
We study charge pumping in generic non-Hermitian settings and show that quantized charge pumping is only guaranteed under a biorthogonal formalism therein, where the charge transpo…
Two-dimensional quantum walk with non-Hermitian skin effects
Tianyu Li, Yong-Sheng Zhang, Wei Yi
We construct a two-dimensional, discrete-time quantum walk exhibiting non-Hermitian skin effects under open-boundary conditions. As a confirmation of the non-Hermitian bulk-boundar…
