Altermagnetic-doping interplay as a route to enhanced d-wave pairing in the Hubbard model
Ji Liu, Jianyu Li, Peng Zhang +2
Altermagnets - collinear, zero-net-moment magnets with momentum-odd spin splitting protected by crystalline symmetries - offer a tunable route to suppress long-range antiferromagne…
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…
Enhancement of d-wave Pairing in Strongly Correlated Altermagnet
Jianyu Li, Ji Liu, Xiaosen Yang +1
Altermagnetism, featuring momentum-dependent spin splitting without net magnetization, has attracted a growing interest for spintronics. We study a Fermi Hubbard model with alterma…
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…
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…
