Scaling of disorder operator at U(1) quantum criticality
Yan-Cheng Wang, Meng Cheng, Zi Yang Meng
We study disorder operator, defined as a symmetry transformation applied to a finite region, across a continuous quantum phase transition in . We show analytically that at…
Vestigial anyon condensation in kagome quantum spin liquids
Yan-Cheng Wang, Zheng Yan, Chenjie Wang +2
We construct a lattice model of topological order (kagome quantum spin liquids) and solve it with unbiased quantum Monte Carlo simulations. A three-stage anyon condensation with tw…
Bosonic SET to SPT Transition under Dyonic LSM Theorem
Yan-Cheng Wang, Xu Yang, Ying Ran +1
Employing large-scale quantum Monte Carlo simulatoins, we study the phase diagram of a quantum spin model which is subject to the recently developed dyonic Lieb-Shultz-Mattis (LSM)…
Dynamical Signature of Symmetry Fractionalization in Frustrated Magnets
Guang Yu Sun, Yan-Cheng Wang, Chen Fang +3
The nontrivialness of quantum spin liquid (QSL) typically manifests in the non-local observables that signifies their existence, however, this fact actually casts shadow on detecti…
