Stripe-Ordered Altermagnetism Emerging from Correlation-Driven Spin-Density-Wave Instability
Zenghui Fan, Jingyao Meng, Tianxing Ma
The paper investigates how a spin-density-wave instability in a Hubbard model for iron pnictides can give rise to a stripe‑ordered altermagnetic insulating phase, using Hartree‑Foc…
Interplay of magnetic and thermodynamic responses in the kagome-triangular system
Zixuan Jia, Lufeng Zhang, Qingzhuo Duan +5
Inspired by the recent experimental progress in pyrochlore derivative RESbAO (A = Mg, Zn), we investigate the Hubbard model on the kagome lattice with an additio…
Time-reversal symmetry breaking superconductivity in the presence of loop-current fluctuations
Zenghui Fan, Runyu Ma, Stefano Chesi +2
Loop currents have been proposed in various superconductors and recently confirmed in kagome materials, raising a fundamental question regarding their intrinsic connection to super…
Magnetic fluctuations near the Van Hove singularity in the kagome-lattice Hubbard model at finite doping
Jingyao Wang, Zixuan Jia, Zenghui Fan +2
The kagome-lattice Hubbard model attracts widespread interest due to its flat-band and Van Hove singularity features, which can give rise to unconventional magnetism. We employ det…
Charge stripe and superconductivity tuned by interlayer interaction in a sign-problem-free bilayer extended Hubbard model
Runyu Ma, Zenghui Fan, Hongxin Liu +2
Competing orders represent a central challenge in understanding strongly correlated systems. In this work, we employ projector quantum Monte Carlo simulations to study a sign-probl…
Breathing-Driven Metal-Insulator Transition in Correlated Kagome Systems
Qingzhuo Duan, Zixuan Jia, Zenghui Fan +4
Inspired by the recent discovery of breathing kagome materials \(\rm Nb_3Cl_8\) and \(\rm Nb_3TeCl_7\), we have explored the influence of the breathing effect on the Hubbard model…
