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…

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…
