Shadow of complex fixed point: Approximate conformality of Q>4 Potts model
Han Ma, Yin-Chen He
We study the famous example of weakly first order phase transitions in the 1+1D quantum Q-state Potts model at Q>4. We numerically show that these weakly first order transitions ha…
Unifying Description of Competing Orders in Two Dimensional Quantum Magnets
Xue-Yang Song, Chong Wang, Ashvin Vishwanath +1
Quantum magnets provide the simplest example of strongly interacting quantum matter, yet they continue to resist a comprehensive understanding above one spatial dimension (1D). In…
From spinon band topology to the symmetry quantum numbers of monopoles in Dirac spin liquids
Xue-Yang Song, Yin-Chen He, Ashvin Vishwanath +1
The interplay of symmetry and topology has been at the forefront of recent progress in quantum matter. Here we uncover an unexpected connection between band topology and the descri…
Field-induced QCD-Chern-Simons quantum criticalities in Kitaev materials
Liujun Zou, Yin-Chen He
Kitaev materials are promising for realizing exotic quantum spin liquid phases, such as a non-Abelian chiral spin liquid. Motivated by recent experiments in these materials, we the…
Reconstructing Entanglement Hamiltonian via Entanglement Eigenstates
W. Zhu, Zhoushen Huang, Yin-chen He
The entanglement Hamiltonian , defined through the reduced density matrix of a subsystem , is an important concept in understanding the nature of quantum entan…
Emergent Multi-flavor QED3 at the Plateau Transition between Fractional Chern Insulators: Applications to graphene heterostructures
Jong Yeon Lee, Chong Wang, Michael P. Zaletel +2
Recent experiments in graphene heterostructures have observed Chern insulators - integer and fractional Quantum Hall states made possible by a periodic substrate potential. Here we…
Entanglement signatures of emergent Dirac fermions: kagome spin liquid & quantum criticality
Wei Zhu, Xiao Chen, Yin-Chen He +1
Quantum spin liquids (QSL) are exotic phases of matter that host fractionalized excitations. It is difficult for local probes to characterize QSL, whereas quantum entanglement can…
