Hidden Symmetry Revealed
In a recent letter by Peter Zalom from FZU, Martin Žonda, and Tomáš Novotný from our department, a novel approach to understanding interacting quantum dots coupled to multiple superconducting leads, based on a so far hidden symmetry, has been unveiled. These hybrid nano systems have the potential to be used as building blocks of the future superconducting electronics devices. As also revealed in the letter, they can be tuned to serve as superconducting diodes or even transistors.
