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…
Self-similar gap dynamics in percolation and rigidity percolation
Mingzhong Lu, Yu-Feng Song, Ming Li +1
Spatial self-similarity is a hallmark of critical phenomena. We investigate the dynamic process of percolation, in which bonds are incrementally inserted to an empty lattice until…
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…
Universality of closed nested paths in two-dimensional percolation
Yu-Feng Song, Jesper Lykke Jacobsen, Bernard Nienhuis +2
Recent work on percolation in [J. Phys. A {\bf 55} 204002] introduced an operator that gives a weight to configurations with `nested paths' (NP), i.e. disjo…
Nature of the mixed-parity pairing of attractive fermions with spin-orbit coupling in optical lattice
Yu-Feng Song, Youjin Deng, Yuan-Yao He
The admixture of spin-singlet and spin-triplet pairing states in superconductors can be typically induced by breaking spatial inversion symmetry. Employing the {\it numerically exa…
Nested Closed Paths in Two-Dimensional Percolation
Yu-Feng Song, Xiao-Jun Tan, Xin-Hang Zhang +3
For two-dimensional percolation on a domain with the topology of a disc, we introduce a nested-path operator (NP) and thus a continuous family of one-point functions $W_k \equiv \l…
