Exciton polariton critical non-Hermitian skin effect with spin-momentum-locked gains

Autor: Xu, Xingran, Tian, Lingyu, An, Zhiyuan, Xiong, Qihua, Ghosh, Sanjib

The critical skin effect, an intriguing phenomenon in non-Hermitian systems, displays sensitivity to system size and manifests distinct dynamical behaviors. In this work, we propose a novel scheme to achieve the critical non-Hermitian skin effect of

An intermediate phase induced by dilution in a correlated Dirac Fermi system

Autor: Tian, Lingyu, Meng, Jingyao, Ma, Tianxing

Publikováno v: Phys. Rev. B 106, 205144(2022)

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 model with the on-site Coulomb repulsion being randomly zero on a fractio

Metal-insulator transition in the disordered Hubbard model of the Lieb lattice

Autor: Li, Yueqi, Tian, Lingyu, Ma, Tianxing, Lin, Hai-Qing

Publikováno v: Phys. Rev. B 106, 205149(2022)

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 characterizes the flat band centered at the Fermi level. By choosing su

Doping-dependent metal-insulator transition in a disordered Hubbard model

Autor: Tian, Lingyu, Li, Yueqi, Liang, Ying, Ma, Tianxing

Publikováno v: Phys. Rev. B 105, 045132(2022)

We study the effect of disorder and doping on the metal-insulator transition in a repulsive Hubbard model on a square lattice using the determinant quantum Monte Carlo method. First, with the aim of making our results reliable, we compute the sign pr
