Ising phase transitions and thermodynamics of correlated fermions in a two-dimensional spin-dependent lattice potential
Zhuotao Xie, Yu-Feng Song, Yuan-Yao He
We present a {\it numerically exact} study of the Hubbard model with spin-dependent anisotropic hopping on the square lattice using auxiliary-field quantum Monte Carlo method. At h…
Thermal Entropy, Density Disorder and Antiferromagnetism of Repulsive Fermions in 3D Optical Lattice
Yu-Feng Song, Youjin Deng, Yuan-Yao He
The celebrated antiferromagnetic (AFM) phase transition was realized in a most recent optical lattice experiment for the 3D fermionic Hubbard model [Shao {\it et al}., Nature {\bf…
Magnetic, thermodynamic, and dynamical properties of the three-dimensional fermionic Hubbard model: A comprehensive Monte Carlo study
Yu-Feng Song, Youjin Deng, Yuan-Yao He
The interplay between quantum and thermal fluctuations can induce rich phenomena at finite temperatures in strongly correlated fermion systems. Here we report a {\it numerically ex…
Extended Metal-Insulator Crossover with Strong Antiferromagnetic Spin Correlation in Half-Filled 3D Hubbard Model
Yu-Feng Song, Youjin Deng, Yuan-Yao He
The Hubbard model at temperatures above the Néel transition, despite being a paramagnet, can exhibit rich physics due to the interplay of Fermi surface, on-site interaction and…
