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…
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…
Flat bands and superconductivity induced by periodic strain in monolayer graphene
Jingyao Meng, Runyu Ma, Tianxing Ma +1
Superconductivity in single-layer graphene has attracted considerable interest. Here, using the determinant quantum Monte Carlo method, we study transitions of superconductivity an…
Supersolid Phase in the Diluted Holstein Model
Jingyao Meng, Yuxi Zhang, Rafael M. Fernandes +2
The Holstein model on a square lattice at half-filling has a well-established finite temperature phase transition to an insulating state with long range charge density wave (CDW) o…
