Ground-state phase diagram and route to supersolidity in a two-component extended Bose-Hubbard model
Xuexin Qiu, Ning Bian, Yang Liu +4
We investigate the ground-state phase diagram of a two-component extended Bose-Hubbard model recently realized with dipolar excitons, using the projected entangled-pair states. For…
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 -- Fermi-Hubbard model
Saisai He, Jize Zhao, Hong-Gang Luo +1
In this work, we revisit the phase diagram of the -- 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, , Nature , 485 (2022)], we study…
Quantum dynamics in a spin-1/2 square lattice -- altermagnet
Yang Liu, Shiqi Shao, Saisai He +4
A key feature of the newly discovered altermagnet is that its spin degeneracy is lifted, although it has an antiferromagnetic order and zero net magnetization. In this work, we inv…
Triple-meron crystal in high-spin Kitaev magnets
Ken Chen, Qiang Luo, Zongsheng Zhou +5
Spin textures with nontrivial topology hold great promise in future spintronics applications since they are robust against local deformations. The meron, as one of such spin textur…
