Anderson Transition and Mobility Edges in a Family of 3D Fractal Lattices
Tianyu Li, Xin Tang, Sheng Liu +1
Anderson localization is fundamentally controlled by dimensionality, yet the nature of the Anderson transition in continuously tunable noninteger dimensions remains largely unexplo…
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…
Simulating Floquet non-Abelian topological insulator with photonic quantum walks
Quan Lin, Tianyu Li, Haiping Hu +2
Floquet non-Abelian topological phases emerge in periodically driven systems and exhibit properties that are absent in their Abelian or static counterparts. Dubbed the Floquet non-…
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…
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…
Engineering Dissipative Quasicrystals
Tianyu Li, Yong-Sheng Zhang, Wei Yi
We discuss the systematic engineering of quasicrystals in open quantum systems where quasiperiodicity is introduced through purely dissipative processes. While the resulting short-…
Simulating non-Hermitian quasicrystals with single-photon quantum walks
Quan Lin, Tianyu Li, Lei Xiao +3
Non-Hermiticity significantly enriches the properties of topological models, leading to exotic features such as the non-Hermitian skin effects and non-Bloch bulk-boundary correspon…
Observation of non-Hermitian topological Anderson insulator in quantum dynamics
Quan Lin, Tianyu Li, Lei Xiao +3
Disorder and non-Hermiticity dramatically impact the topological and localization properties of a quantum system, giving rise to intriguing quantum states of matter. The rich inter…
Detecting non-Bloch topological invariants in quantum dynamics
Kunkun Wang, Tianyu Li, Lei Xiao +3
Non-Bloch topological invariants preserve the bulk-boundary correspondence in non-Hermitian topological systems, and are a key concept in the contemporary study of non-Hermitian to…
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…
