Thermal Signatures of the Slater-Mott Crossover in the Hubbard Model: From Double Occupancy to Antiferromagnetic Correlation Length
Mingzhong Lu, Yu-Feng Song, Youjin Deng +1
The interaction-driven crossover from a Slater insulator to a Mott insulator in the Néel-ordered ground state of the Hubbard model is a fundamental paradigm of strongly correlated…
Computation of thermal entropy for the doped Hubbard Model
Yu-Feng Song, Youjin Deng, Yuan-Yao He
We develop a highly efficient framework for computing the thermal entropy in the doped Fermi-Hubbard model within the grand-canonical ensemble. The framework comprises four calcula…
Quantum Monte Carlo study of the metal-insulator crossover in the square-lattice Hubbard model
Mingzhong Lu, Yu-Feng Song, Youjin Deng +1
The interaction-driven evolution from a Fermi liquid to a Mott insulator is a hallmark of strongly correlated fermion systems. In this work, we present a {\it numerically unbiased}…
High-precision Dynamic Monte Carlo Study of Rigidity Percolation
Mingzhong Lu, Yufeng Song, Qiyuan Shi +2
Rigidity percolation provides an important basis for understanding the onset of mechanical stability in disordered materials. While most studies on the triangular lattice have focu…
Spin-triplet pairing instability in a two-dimensional repulsive Hubbard model
Xing-Can Liu, Yu-Feng Song, Yuan-Yao He +2
The search for superconductivity with unconventional pairing symmetry has been a central focus in the study of strongly correlated electron systems. In this work, we report a numer…
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…
