Oriented Triplet -Wave Pairing from Fermi surface Anisotropy and Nonlocal Attraction
Shuning Tan, Ji Liu, Minghuan Zeng +3
Using constrained-path quantum Monte Carlo, we map the ground-state phase diagram versus the nearest-neighbor (NN) attraction and spin-dependent hopping anisotropy for the…

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…

Pairing phase diagram for electron-doped cuprates in the square-lattice Hubbard model
Zhangkai Cao, Shuning Tan, Ji Liu +4
Motivated by significant discrepancies between experimental observations of electron-doped cuprates and numerical results of the Hubbard model, we investigate the role of nearest-n…
