Dirac fermions with plaquette interactions. III. SU(N) phase diagram with Gross-Neveu criticality and first-order phase transition
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
Inspired by our recent works[1, 2] of SU(2) and SU(4) Dirac fermions subjected to plaquette interactions on square lattice, here we extend the large-scale quantum Monte Carlo inves…
Dirac fermions with plaquette interactions. II. SU(4) phase diagram with Gross-Neveu criticality and quantum spin liquid
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
At sufficiently low temperatures, interacting electron systems tend to develop orders. Exceptions are quantum critical point (QCP) and quantum spin liquid (QSL), where fluctuations…
Sign Problem in Quantum Monte Carlo Simulation
Gaopei Pan, Zi Yang Meng
Sign problem in quantum Monte Carlo (QMC) simulation appears to be an extremely hard yet interesting problem. In this article, we present a pedagogical overview on the origin of th…
Dirac fermions with plaquette interactions. I. SU(2) phase diagram with Gross-Neveu and deconfined quantum criticalities
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
We investigate the ground state phase diagram of an extended Hubbard model with -flux hopping term at half-filling on a square lattice, with unbiased large-scale auxiliary-field…
