Finite-momentum superconductivity with singlet-triplet mixing in an altermagnetic metal: A pairing instability analysis
Hui Hu, Zhao Liu, Jia Wang +2
We analyze the pairing instability of an altermagnetic metal on a square lattice driven by an attractive nearest-neighbor interaction. This interaction enables multiple pairing cha…

Altermagnetism-driven FFLO superconductivity in finite-filling 2D lattices
Xia-Ji Liu, Hui Hu
We systematically investigate the emergence of finite-momentum Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconductivity in a square lattice Hubbard model with finite filling, driv…

Finite-momentum bound pairs of two electrons in an altermagnetic metal
Hui Hu, Zhao Liu, Jia Wang +1
We solve the two-electron problem on a square lattice with d-wave altermagnetism, considering both on-site and nearest-neighbor attractive interactions. The altermagnetic spin-spli…
