Steady-state topological order
Xu-Dong Dai, Zijian Wang, He-Ran Wang +1
We investigate a generalization of topological order from closed systems to open systems, for which the steady states take the place of ground states. We construct typical lattice…
Topologically Ordered Steady States in Open Quantum Systems
Zijian Wang, Xu-Dong Dai, He-Ran Wang +1
The interplay between dissipation and correlation can lead to novel emergent phenomena in open systems. Here we investigate ``steady-state topological order'' defined by the robust…
Non-Bloch dynamics and topology in a classical non-equilibrium process
Bo Li, He-Ran Wang, Fei Song +1
The non-Hermitian skin effect refers to the accumulation of eigenstates near the boundary in open boundary lattice models, which can be systematically characterized using the non-B…
Embedding Quantum Many-Body Scars into Decoherence-Free Subspaces
He-Ran Wang, Dong Yuan, Shun-Yao Zhang +3
Quantum many-body scars are non-thermal excited eigenstates of non-integrable Hamiltonians, which could support coherent revival dynamics from special initial states when scars for…
Scale-free localization and PT symmetry breaking from local non-Hermiticity
Bo Li, He-Ran Wang, Fei Song +1
We show that a local non-Hermitian perturbation in a Hermitian lattice system generically induces scale-free localization for the continuous-spectrum eigenstates. When the perturba…
Scale-free non-Hermitian skin effect in a boundary-dissipated spin chain
He-Ran Wang, Bo Li, Fei Song +1
We study the open XXZ spin chain with a PT-symmetric non-Hermitian boundary field. We find an interaction-induced scale-free non-Hermitian skin effect by using the coordinate Bethe…
