Simulation of Fermionic and Bosonic Critical Points with Emergent SO(5) Symmetry
Toshihiro Sato, Zhenjiu Wang, Yuhai Liu +4
We introduce a model of Dirac fermions in 2+1 dimensions with a semimetallic, a quantum spin-Hall insulating (QSHI), and an s-wave superconducting (SSC) phase. The phase diagram fe…
Validity of SLAC fermions for the (1 + 1)-dimensional helical Luttinger liquid
Zhenjiu Wang, Fakher Assaad, Maksim Ulybyshev
The Nielson-Ninomiya theorem states that a chirally invariant free fermion lattice action, which is local, translation invariant, and real necessarily has fermion doubling. The SLA…
Bandwidth controlled quantum phase transition between an easy-plane quantum spin Hall state and an s-wave superconductor
Disha Hou, Yuhai Liu, Toshihiro Sato +3
The quantum spin Hall state can be understood in terms of spontaneous O(3) symmetry breaking. Topological skyrmion configurations of the O(3) order parameter vector carry a charge…
Quantum Monte Carlo at the Graphene Quantum Hall Edge
Zhenjiu Wang, David J. Luitz, Inti Sodemann Villadiego
We study a continuum model of the interface of graphene and vacuum in the quantum hall regime via sign-problem-free quantum Monte Carlo, allowing us to investigate the interplay of…
