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…

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}…
