Our group will be showing a comprehensive presence at the upcoming DPG Spring Meeting in Regensburg (March 2025) showcasing our work on spin-orbit torques, the unconventional Josephson supercurrent diode effect, altermagnet/superconductor/altermagnet junctions, as well as our first-principles studies of radial Rashba spin-orbit coupling in twisted heterostructures.

The schedule with our group's contributions can be found here.

After predicting that the competition between conventional and chiral spin-orbit fields in Josephson junctions can lead to the unconventional supercurrent diode effect (see below), we are exploring fundamental ways to disentangle both types of spin-orbit coupling in real materials from transport measurements focusing at single-interface ferromagnet/superconductor junctions and also addressing interference with hypothetic Dresselhaus interactions.

Our article has been published in Physical Review B.

The organizers have invited Dr. Andreas Costa to showcase our theoretical studies on the Josephson supercurrent diode effect at the first Heraeus-Lorentz workshop "Superconductivity in symmetry-broken and low-dimensional systems" in Leiden.
