The ability to control superconducting pairing symmetry is crucial for designing unconventional and topological superconductors, yet practical tuning parameters beyond chemical dop…
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…
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…
Disorder-dependent superconducting pairing symmetry in doped graphene
