Superconducting diode effects
–, – (all times are in CET timezone)
In the last few years, experimental breakthroughs in the field of non-reciprocal superconductivity have led to the realization of the superconducting diode effect in both bulk superconducting films and Josephson junctions (i.e., Josephson diodes), both with and without an applied magnetic field to break time reversal symmetry. These results raise fundamental questions as to the origins and mechanisms of the different superconducting diode effects as well as open the door to game-changing advancements in superconducting electronics for technological applications. In this workshop, we bring together experimentalists creating and exploring novel superconducting diodes as well as theorists explaining and predicting these effects. Through a series of seminars and discussions, we will compile the status of the field and chart a path for the future.

Satellite talks
We welcome interested colleagues to deliver a satellite talk on closely related research. We will announce these talks to all participants and use them in guiding the discussions. To let us know about your plan to give a talk, send us an email. Then you may either:
- register to give a talk in the Speakers' Corner seminar series
- share a YouTube link
- send us a recording
We will include the satellite talks in this workshop webpage.
