Invited Talk at APS March Meeting

The American Physical Society (APS) has invited Dr. Paulo E. Faria Junior, Research Associate in our group, for an Invited Talk at the upcoming APS March Meeting in Minneapolis (March 2024).

The talk will cover the theoretical developments of the valley Zeeman effect that elucidate and predict elusive physical phenomena in 2D van-der-Waals systems.

The abstract can be found here.

Walter-Schottky-Prize for Dr. Nicola Paradiso

Our collaborator Dr. Nicola Paradiso from the Strunk Group in Regensburg will be awarded the Walter-Schottky-Prize 2024 at the upcoming DPG Spring Meeting in Berlin for "his outstanding works on the Josephson [supercurrent] diode effect that will open new perspectives for superconducting quantum electronics".

The theory support for Dr. Paradiso's groundbreaking experimental studies has been provided by Dr. Andreas Costa, Postdoc in our group, and Dr. Denis Kochan (Slovak Academy of Sciences in Bratislava).

Congratulations, Nicola!
