[…] something unexpected occurred. The disappearance did not take place gradually but abruptly. […] Thus the mercury at 4.2K4.2K4.2K has entered a new state, which, owing to its particular electrical …
2. Unconventional Superconductors
Introduction Superconductivity beyond the conventional BCS paradigm reveals rich physics tied to symmetry, topology, and multicomponent order parameters. These unconventional superconductors often break additional …
3. Loop Supercurrents
Motivation and Background Superconductivity, the phenomenon of zero electrical resistance and perfect diamagnetism below a critical temperature TcT_cTc, has been studied extensively since its discovery over a century …
