Impurity screening by defects in (1+1) quantum critical systems
Ying-Hai Wu, Yueshui Zhang, Hong-Hao Tu +1
We propose a novel mechanism of impurity screening in (1+1) quantum critical states described by conformal field theories (CFTs). An impurity can be screened if it has the same…
Superradiant phase transition induced by the indirect Rabi interaction
Wen Huang, Ying Wu, Xin-You Lü
We theoretically study the superradiant phase transition (SPT) in an indirect Rabi model, where both a two-level system and a single mode bosonic field couple to an auxiliary boson…
Continuous phase transitions between fractional quantum Hall states and symmetry-protected topological states
Ying-Hai Wu, Hong-Hao Tu, Meng Cheng
We study quantum phase transitions in Bose-Fermi mixtures driven by interspecies interaction in the quantum Hall regime. In the absence of such an interaction, the bosons and fermi…
Topological states in double monolayer graphene
Ying-Hai Wu
Motivated by the experiments on double monolayer graphene that observe a variety of fractional quantum Hall states [Liu et al., Nat. Phys. 15, 893 (2019); Li et al., Nat. Phys. 15,…
Two-component parton fractional quantum Hall state in graphene
Ying-Hai Wu
We study the fractional quantum Hall states in graphene observed by Zibrov et al. [Nat. Phys. 14, 930 (2018)]. The parton construction is employed to provide a valley…
Non-Abelian topological order with SO(5) chiral edge states
Ying-Hai Wu, Hong-Hao Tu
We consider a chiral spin liquid constructed using the parton theory. This state supports non-Abelian anyons and neutral fermions, which share some similarities with the celebrated…
