From Bosonic Topological Transition to Symmetric Fermion Mass Generation
Yi-Zhuang You, Yin-Chen He, Ashvin Vishwanath +1
The bosonic topological transition (BTT) is a quantum critical point between the bosonic symmetry protected topological phase and the trivial phase. In this work, we derive a descr…
Critical behavior of the QED-Gross-Neveu model: Duality and deconfined criticality
Lukas Janssen, Yin-Chen He
We study the critical properties of the QED-Gross-Neveu model with flavors of two-component Dirac fermions coupled to a massless scalar field and a U(1) gauge field. For $…
Stability of the spin- kagome ground state with breathing anisotropy
Cécile Repellin, Yin-Chen He, Frank Pollmann
We numerically study the spin- breathing kagome lattice. In this variation of the kagome Heisenberg antiferromagnet, the spins belonging to upward and downward facing triangle…
Continuous easy-plane deconfined phase transition on the kagome lattice
Xue-Feng Zhang, Yin-Chen He, Sebastian Eggert +2
We use large scale quantum Monte-Carlo simulations to study an extended Hubbard model of hardcore bosons on the kagome lattice. In the limit of strong nearest-neighbor interactions…
Symmetric Fermion Mass Generation as Deconfined Quantum Criticality
Yi-Zhuang You, Yin-Chen He, Cenke Xu +1
Massless 2+1D Dirac fermions arise in a variety of systems from graphene to the surfaces of topological insulators, where generating a mass is typically associated with breaking a…
Realizing and Adiabatically Preparing Bosonic Integer and Fractional Quantum Hall states in Optical Lattices
Yin-Chen He, Fabian Grusdt, Adam Kaufman +2
We study the ground states of 2D lattice bosons in an artificial gauge field. Using state of the art DMRG simulations we obtain the zero temperature phase diagram for hardcore boso…
