Tunable quasiparticle trapping in Meissner and vortex states of mesoscopic superconductors

Abstract

Excessive excitation induced by overheating may deteriorate the resistance-free operation of superconductor-based devices. Here, Taupin et al. propose an effective control of excess quasiparticles and their spatial distribution in a mesoscopic superconducting disc by applying a small magnetic field.
