Improved scaling of the entanglement entropy of quantum antiferromagnetic Heisenberg systems
Zehui Deng, Lu Liu, Wenan Guo +1
In this paper, we derive corrections to the subleading logarithmic term of the entanglement entropy in systems with spontaneous broken continuous symmetry. Using quantum Monte Carl…
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…
Extraordinary surface critical behavior induced by symmetry-protected topological state of a two-dimensional quantum magnet
Zhe Wang, Fan Zhang, Wenan Guo
Using Quantum Monte Carlo simulations, we study spin-1/2 diagonal ladders coupled by ferromagnetic Heisenberg interactions. The model can also be viewed as usual ladders with ferro…
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…
Bulk and Surface Critical Behaviors of quantum Heisenberg antiferromagnet on a two-dimensional coupled diagonal ladders
Zhe Wang, Fan Zhang, Wenan Guo
Using Quantum Monte Carlo simulations, we study the spin-1/2 Heisenberg model on a two-dimensional lattice formed by coupling diagonal ladders. The model hosts an antiferromagnetic…
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…
