Extracting conserved operators from a projected entangled pair state
Wen-Tao Xu, Miguel FrÃas Pérez, Mingru Yang
Given a tensor network state, how can we determine conserved operators (including Hamiltonians) for which the state is an eigenstate? We answer this question by presenting a method…
Continuous topological phase transition between topologically ordered phases
Qi Zhang, Wen-Tao Xu
Topological phase transitions beyond anyon condensation remain poorly understood. A notable example is the transition between the toric code (TC) and double semion (DS) phases, whi…
Dipole condensates in synthetic rank-2 electric fields
Jiali Zhang, Wenhui Xu, Qi Zhou +1
Dipole condensates, formed from particle-hole pairs, represent a unique class of charge-neutral quantum fluids that evade conventional vector gauge fields, making their electrodyna…
Excitonic skin effect
Wenhui Xu, Qi Zhou
We show that strong interactions combined with band-dependent imaginary vector potentials give rise to boundary localization of particle-hole pairs, which we term the excitonic ski…
