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…
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…
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…
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…
