Mutual enhancement of altermagnetism and ferroelectricity
Chi Sun, Jacob Linder
We consider theoretically the possibility of coexisting ferroelectric and metallic altermagnetic order, which has recently been predicted in insulating and semiconducting systems v…

Josephson transistor and robust supercurrent enhancement with spin-split superconductors
Chi Sun, Jacob Linder
We theoretically investigate the supercurrent flow in a Josephson junction consisting of two spin-split superconductors combined by a normal metal weak link. The normal metal may b…
