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…
