Variation of Electron-electron interaction in pyrochlore structures
Jianyu Li, Ji Liu, Mingjun Han +3
We conduct a comprehensive \textit{ab initio} investigation of electron-electron interactions within the pyrochlore structures of RRuO, RIrO, CaRuO$…
p-wave superconductivity induced by nearest-neighbor attraction in the square-lattice extended Hubbard model
Zhangkai Cao, Jianyu Li, Jiahao Su +2
The two-dimensional (2D) Hubbard model is widely believed to contain the key ingredients of high-temperature superconductivity in cuprate materials. Here, we report a constrained p…
dx2-y2-wave Bose Metal induced by the next-nearest-neighbor hopping t'
Zhangkai Cao, Jianyu Li, Jiahao Su +2
Superconductivity arises when electrons form Cooper pairs with phase coherence. In contrast, a lack of phase coherence in Cooper pairs can lead to an uncondensed metallic ground st…
Exotic d-wave Cooper Pair Bose Metal in two dimensions
Zhangkai Cao, Jiahao Su, Jianyu Li +5
The study of non-Fermi liquids sheds light on unconventional phenomena in condensed matter systems that lie beyond the scope of Landau Fermi liquid theory. One intriguing example i…
