Caution on Gross-Neveu criticality with a single Dirac cone: Violation of locality and its consequence of unexpected finite-temperature transition
Yuan Da Liao, Xiao Yan Xu, Zi Yang Meng +1
Lately there are many SLAC fermion investigations on the (2+1)D Gross-Neveu criticality of a single Dirac cone [1,2]. While the SLAC fermion construction indeed gives rise to the l…
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…
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…
