Strong enhancement of d-wave superconductivity in an extended checkerboard Hubbard ladder

Xichen Huang, Saisai He, Jize Zhao +1

By employing the density-matrix renormalization group method, we study an extended checkerboard Hubbard model on the two-leg ladder, which includes an intraplaquette nearest-neighb…

Altermagnetism and beyond in the $t$ - $t^{'}$ - $δ$ Fermi-Hubbard model

Saisai He, Jize Zhao, Hong-Gang Luo +1

In this work, we revisit the phase diagram of the $t$ - $t^{'}$ - $δ$ Fermi-Hubbard model on the square lattice to gain a more comprehensive understanding of this correlated model a…

Emergent supercounterfluid and quantum phase diagram of two-component interacting bosons in one-dimensional optical lattice

Saisai He, Yang Liu, Bin Xi +3

Motivated by a recent experiment that realizes nearest-neighbor dipolar couplings in an optical lattice [C. Lagoin, $et al.$ , Nature $609$ , 485 (2022)], we study…
