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…

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…
