Superconducting Qubits with Altermagnetic Josephson Junctions
Johanne Bratland Tjernshaugen, Morten Amundsen, Jacob Linder
Identifying a materials platform for creating qubits that are both tunable and resilient towards environmental noise is one of the main hurdles that need to be overcome to realize…
Real-space microscopic description of laser-pulse induced melting of superconductivity
Karl Bergson Hallberg, Guillermo Nava Antonio, Chiara Ciccarelli +1
Quenching quantum order via laser pulses has proven a useful tool to access exotic physical effects in systems that are strongly perturbed out of equilibrium. However, theoretical…
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…
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…
