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…
