An intermediate phase induced by dilution in a correlated Dirac Fermi system
Lingyu Tian, Jingyao Meng, Tianxing Ma
Substituting magnetic ions with nonmagnetic ions is a new way to study dilution. Using determinant quantum Monte Carlo calculations, we investigate an interacting Dirac fermion mod…

Metal-insulator transition in the disordered Hubbard model of the Lieb lattice
Yueqi Li, Lingyu Tian, Tianxing Ma +1
Using the determinant quantum Monte Carlo method, we investigate the metal-insulator transition in the interacting disordered Hubbard model of a Lieb lattice, in which the system c…
