Mobility edges and critical regions in periodically kicked incommensurate optical Raman lattice
Yucheng Wang
Conventionally the mobility edge (ME) separating extended states from localized ones is a central concept in understanding Anderson localization transition. The critical state, bei…
Two dimensional vertex-decorated Lieb lattice with exact mobility edges and robust flat bands

The mobility edge (ME) that marks the energy separating extended and localized states is a central concept in understanding the metal-insulator transition induced by disordered or…
Quantum phase with coexisting localized, extended, and critical zones
Yucheng Wang, Long Zhang, Wei Sun +2
Conventionally a mobility edge (ME) marks a critical energy that separates two different transport zones where all states are extended and localized, respectively. Here we propose…
Emergent gapless topological Luttinger liquid
Sen Niu, Yucheng Wang, Xiong-Jun Liu
Gapless Luttinger liquid is conventionally viewed as topologically trivial, unless it hosts degenerate ground states and or entanglement spectrum, which necessitates partial bulk d…

The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Realization and detection of non-ergodic critical phases in optical Raman lattice
Yucheng Wang, Long Zhang, Sen Niu +2
The critical phases, being delocalized but non-ergodic, are fundamental phases which are different from both the many-body localization and ergodic extended quantum phases, and hav…
Many-body critical phase: extended and nonthermal
Yucheng Wang, Chen Cheng, Xiong-jun Liu +1
The transition between ergodic phase and many-body localization (MBL) phase lies at the heart in understanding quantum thermalization of many-body systems. Here we predict a many-b…
