Abstract

We have studied experimentally the physics of the destructive regime, the loss of superconductivity around half-flux quanta, in ultrathin, doubly connected superconducting cylinders when their diameters become smaller than the superconducting coherence length at zero temperature. We show that the transition from the superconducting to normal behavior at the onset of the destructive regime is very sharp. Near this zero-temperature quantum phase transition, there appears to be a phase separation in which normal regions nucleate in a homogeneous superconducting cylinder.
