New scientific paper by our colleagues has been published in Nature Physics! The study reveals a departure from the conventional understanding of quantum phase transitions. By measuring the plasmon spectrum in superconducting microwave resonators, the authors demonstrate a sudden jump in superfluid stiffness and transition temperature at critical disorder. This first-order quantum phase transition sheds light on the role of repulsive interactions between Cooper pairs and the interplay between superconductivity and the insulating Cooper-pair glass phase. The findings raise fundamental questions about the impact of disorder on quantum phase transitions and have important implications for quantum circuits.
We take great pride in seeing the groundbreaking research of our colleagues featured in the world’s leading scientific journals!
