Interfacial orbital transmission, conversion, and mechanical torque in metals
Chi Sun, Dongwook Go, Yuriy Mokrousov +2
Interfacial orbital transport remains far less understood than its bulk counterpart despite its central role in orbitronic experiments. Here, we theoretically investigate the trans…
Multipolar orbital relaxation of the states
Aurélien Manchon, Xiaobai Ning, Chi Sun +3
Using a nonperturbative approach, the relaxation rate of orbital dipolar and quadrupolar moments is computed analytically for the t2g states. In the presence of short-range impurit…
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…
Voltage-tunable spin supercurrent nonreciprocity reaching 100% efficiency
Chi Sun, Johanne Bratland Tjernshaugen, Jacob Linder
The superconducting version of a diode effect has been the subject of extensive research in the past few years. So far, the focus has almost exclusively been on charge transport, b…
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…
