Inducing metal-insulator transition via disorder in correlated kagome systems
Qingzhuo Duan, Hongdao Zhuge, Zixuan JIa +1
The metal-insulator transition is often accompanied by fascinating quantum phenomena, including superconducting domes, antiferromagnetic phase transitions, and quantum spin liquids…
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…
Precompression engineering of metal-insulator transition and magnetism in designed breathing kagome systems
Qingzhuo Duan, Hongdao Zhuge, Ying Liang +1
Kagome materials featuring dispersive Dirac cones and topological flat bands exhibit unique electronic and magnetic properties. However, kagome compounds with tunable electrical co…
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…
