Edge modes of topological Mott insulators and deconfined quantum critical points
Yuhai Liu, Toshihiro Sato, Disha Hou +3
Topology and anomalies lead to edge modes that can interact with critical bulk fluctuations. To study this setup, pertaining to boundary criticality, we consider a model exhibiting…
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…
