Gross-Neveu Heisenberg criticality: dynamical generation of quantum spin Hall masses
Yuhai Liu, Zhenjiu Wang, Toshihiro Sato +2
We consider fermions on a honeycomb lattice supplemented by a spin invariant interaction that dynamically generates a quantum spin Hall insulator. This lattice model provides an in…
Phases of the (2+1) dimensional SO(5) non-linear sigma model with topological term
Zhenjiu Wang, Michael P. Zaletel, Roger S. K. Mong +1
We use the half-filled zeroth Landau level in graphene as a regularization scheme to study the physics of the SO(5) non-linear sigma model subject to a Wess-Zumino-Witten topologic…
Superconductivity from the Condensation of Topological Defects in a Quantum Spin-Hall Insulator
Yuhai Liu, Zhenjiu Wang, Toshihiro Sato +4
The discovery that spin-orbit coupling can generate a new state of matter in the form of quantum spin-Hall (QSH) insulators has brought topology to the forefront of condensed matte…
Finite-size effects in canonical and grand-canonical quantum Monte Carlo simulations for fermions
Zhenjiu Wang, Fakher F. Assaad, Francesco Parisen Toldin
We introduce a quantum Monte Carlo method at finite temperature for interacting fermionic models in the canonical ensemble, where the conservation of the particle number is enforce…
