Two-body interaction induced phase transitions and intermediate phases in nonreciprocal non-Hermitian quasicrystals
Yalun Zhang, Longwen Zhou
Non-Hermitian phenomena, such as exceptional points, non-Hermitian skin effects, and topologically nontrivial phases have attracted continued attention. In this work, we reveal how…
Topological edge states at Floquet quantum criticality
Longwen Zhou, Jiangbin Gong, Xue-Jia Yu
Topologically protected edge states exactly at topological phase boundaries challenge the conventional belief that topological states must be associated with a bulk energy gap. Bec…
Quantum geometry and geometric entanglement entropy of one-dimensional Floquet topological matter
Longwen Zhou
The geometry of quantum states could offer indispensable insights for characterizing the topological properties, phase transitions and entanglement nature of many-body systems. In…
Multiple topological transitions and spectral singularities in non-Hermitian Floquet systems
Weiwei Zhu, Longwen Zhou, Linhu Li +1
The interplay between Floquet driving and non-Hermitian gain/loss could give rise to intriguing phenomena including topological funneling of light, edge-state delocalization, anoma…
Entanglement phase transitions in non-Hermitian Kitaev chains
Longwen Zhou
The intricate interplay between unitary evolution and projective measurements could induce entanglement phase transitions in the nonequilibrium dynamics of quantum many-particle sy…
