Self-Learning Determinantal Quantum Monte Carlo Method
Xiao Yan Xu, Yang Qi, Junwei Liu +2
Self-learning Monte Carlo method [arXiv:1610.03137, 1611.09364] is a powerful general-purpose numerical method recently introduced to simulate many-body systems. In this work, we i…
Non-Fermi-liquid at (2+1)d ferromagnetic quantum critical point
Xiao Yan Xu, Kai Sun, Yoni Schattner +2
We construct a two-dimensional lattice model of fermions coupled to Ising ferromagnetic critical fluctuations. Using extensive sign-problem-free quantum Monte Carlo simulations, we…
Competing pairing channels in the doped honeycomb lattice Hubbard model
Xiao Yan Xu, Stefan Wessel, Zi Yang Meng
Proposals for superconductivity emerging from correlated electrons in the doped Hubbard model on the honeycomb lattice range from chiral singlet to triplet pairing, d…
Topological phase transitions with SO(4) symmetry in (2+1)d interacting Dirac fermions
Xiao Yan Xu, K. S. D. Beach, Kai Sun +2
Interaction-driven topological phase transitions in Dirac semimetals are investigated by means of large-scale quantum Monte Carlo (QMC) simulations. The interaction among Dirac fer…
