Variation of Bose surface by Filling in Cooper pair Bose metal
Jiahao Su, Ji Liu, Jianyu Li +3
The Cooper pair Bose metal (CPBM) is a non-superfluid quantum phase in which uncondensed fermion pairs form a "Bose surface" in momentum space. We investigate the CPBM in the two-d…

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…

Ab Initio Studies on Interactions in KC under High Pressure
Jianyu Li, Zhangkai Cao, Jiahao Su +5
Fullerene solids doped with alkali metals (AC, A = K, Rb, Cs) exhibit a superconducting transition temperature () as high as 40 K, and their unconventional supercon…
