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}…

Quasi-one-dimensional spin excitations in the iron pnictide NaFe $_{0.53}$ Cu $_{0.47}$ As

Yifan Wang, David W. Tam, Weiyi Wang +8

Spectroscopic measurements in model one-dimensional (1D) correlated systems offer insights for understanding their two-dimensional counterparts, which include the cuprate and iron…

Quasi-two-dimensional Antiferromagnetic Spin Fluctuations in the Spin-triplet Superconductor Candidate CeRh $_{2}$ As $_{2}$

Tong Chen, Hasan Siddiquee, Zack Rehfuss +10

The tetragonal heavy-fermion superconductor CeRh $_{2}$ As $_{2}$ ( $T_{c} = 0.3$ K) exhibits an exceptionally high critical field of 14 T for $B ∥ c$ . It under…
