The antiferromagnetic Chern insulator phase in the Kane-Mele-Hubbard model
Bao-Qing Wang, Can Shao, Takami Tohyama +2
The emergence of the antiferromagnetic (AFM) Chern insulator (AFCI) phase in the Kane-Mele-Hubbard (KMH) model with a finite sublattice potential is investigated. The AFCI, charact…
Characterizing spin ordering via maximal row correlation in classical spin models
Yong-Yi Tang, Yin Zhong, Hantao Lu
An order parameter, termed the maximal row correlation, is proposed for classical spin systems. Monte Carlo simulations on various Potts models suggest that this order parameter is…
Energy Dispersion, Superconductivity and Magnetic Fluctuations in Stacked Altermagnetism Materials
Jun Chang, Hantao Lu, Jize Zhao +2
Recently, altermagnetism (AM) has emerged as a new category of magnetism, alongside conventional antiferromagnetism (AFM) and ferromagnetism (FM). In an AM, superconductivity (SC)…
A new pathway to impact ionization in a photo-excited one-dimensional ionic Hubbard model
Zhenyu Cheng, Li Yang, Xiang Hu +3
Using the time-dependent Lanczos method, we study the non-equilibrium dynamics of the half-filled one-dimensional ionic Hubbard model, deep within the Mott insulating regime, under…
The single-particle spectral function of the extended Peierls-Hubbard model at half-filling and quarter-filling
Ren-He Xu, Hantao Lu, Takami Tohyama +1
By utilizing the twisted boundary conditions in the exact diagonalization method, we investigate the single-particle spectral function of the extended Peierls-Hubbard model at both…
Topological phase in the extended Haldane-Hubbard model with sublattice-dependent repulsion
Bao-Qing Wang, Can Shao, Takami Tohyama +2
We study the ground-state phase diagram of the half-filled extended Haldane-Hubbard model on the honeycomb lattice with sublattice-dependent on-site repulsion () us…
Photoinduced phase switching from Mott insulator to metallic state in the quarter-filled Peierls-Hubbard model
Can Shao, Takami Tohyama, Hantao Lu
Utilizing the exact diagonalization method, we investigate the one-dimensional Peierls-Hubbard model at quarter filling, where it manifests as an antiferromagnetic Mott insulator i…
Site-selective doublon-holon dynamics in a pumped one-dimensional Hubbard superlattice with staggered Coulomb interactions
Zhenyu Cheng, Ying Li, Hantao Lu +4
Doublon-holon dynamics is investigated in a pumped one-dimensional Hubbard model with a staggered on?site Coulomb interaction at half-filling. When the system parameters are set to…
