Signatures of a Lifshitz transition in pressurized electron-doped cuprate
Jinyu Zhao, Shu Cai, Zhaoyu Liu +14
It is well known that the electronic structure of hole-doped cuprate superconductors is tunable through both chemical doping and external pressure, which frequently offer us new in…

Fulde-Ferrell-Larkin-Ovchinnikov States and Topological Bogoliubov Fermi Surfaces in Altermagnets: an Analytical Study
Zhao Liu, Hui Hu, Xia-ji Liu
We present an analytical study of the ground-state phase diagram for dilute two-dimensional spin-1/2 Fermi gases exhibiting -wave altermagnetic spin splitting under -wave pai…

Unconventional superconductivity of an altermagnetic metal: Polarized BCS and inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov states
Hui Hu, Zhao Liu, Xia-Ji Liu
We investigate the superconductivity of two-dimensional spin-1/2 Fermi systems with -wave altermagnetism under external magnetic field near zero temperature. At large altermagne…
