Phonon relaxation of subgap levels in superconducting quantum point contacts
D. A. Ivanov, M. V. Feigel'man
Superconducting quantum point contacts are known to possess two subgap states per each propagating mode. In this note we compute the low-temperature relaxation rate of the upper su…
Two-level Hamiltonian of a superconducting quantum point contact
D. A. Ivanov, M. V. Feigel'man
In a superconducting quantum point contact, dynamics of the superconducting phase is coupled to the transitions between the subgap states. We compute this coupling and derive the t…
Level statistics inside the core of a superconductive vortex
M. A. Skvortsov, V. E. Kravtsov, M. V. Feigel'man
Microscopic theory of the type of Efetov's supermatrix sigma-model is constructed for the low-lying electron states in a mixed superconductive-normal system with disorder. The deve…
Quantum Superconductor-Metal Transition in a 2D Proximity-Coupled Array
M. V. Feigel'man, A. I. Larkin
We construct a theory of quantum fluctuatons in a regular array of small superconductive islands connected via low-resistance tunnel contacts to a dirty thin metal film. Electron-e…
