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…

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…

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…
