Effective model for superconductivity in magic-angle graphene
Disha Hou, Yuhai Liu, Toshihiro Sato +3
We carry out large-scale quantum Monte Carlo simulations of a candidate field theory for the onset of superconductivity in magic-angle twisted bilayer graphene. The correlated insu…
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…
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…
Negative sign free formulations of generalized Kitaev models with higher symmetries
Toshihiro Sato, Fakher F. Assaad
We provide a negative-sign-free formulation of the auxiliary field quantum Monte Carlo algorithm for generalized Kitaev models with higher symmetries. Our formulation is based on t…
Thermodynamic and Dynamical Signatures of a Quantum Spin-Hall Insulator to Superconductor Transition
Martin Hohenadler, Yuhai Liu, Toshihiro Sato +3
Thermodynamic and dynamical properties of a model of Dirac fermions with a deconfined quantum critical point (DQCP) separating an interaction-generated quantum spin-Hall insulator…
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…
