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…
Evolution of magnetic correlation in doped Hubbard model with altermagnetic spin splitting
Yinlong Li, Rana Imran Mushtaq, Ji Liu +4
The evolution of magnetic correlation in strongly correlated electron systems with altermagentic spin splitting remains largely unexplored. Here we investigate how spin splitting g…
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…
Ab Initio Studies on Interactions in KC under High Pressure
Jianyu Li, Zhangkai Cao, Jiahao Su +5
Fullerene solids doped with alkali metals (AC, A = K, Rb, Cs) exhibit a superconducting transition temperature () as high as 40 K, and their unconventional supercon…
