Pairing order and condensate fraction across the BCS-BEC crossover in the two-dimensional attractive Hubbard model
Hao Du, Qian Sun, Zhuotao Xie +1
We report a systematic study of the superconducting ground state in the two-dimensional attractive Hubbard model, employing the {\it numerically exact} auxiliary-field quantum Mont…
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…
Nagaoka supermetal in the particle-doped triangular Hubbard model
Rui Cao, Xiangyue Zhang, Hui Tan +4
While the interplay of correlations and geometric frustration in doped Mott insulators provides a fertile ground for exotic quantum phases, the nature of the metallic state emergin…
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}…
