Andreev Spectroscopy for Superconducting Phase Qubits
Mikhail V. Feigel'man, Lev B. Ioffe, Vadim B. Geshkenbein +1
We propose a new method to measure the coherence time of superconducting phase qubits based on the analysis of the magnetic-field dependent dc nonlinear Andreev current across a hi…
Proximity Effect in Presence of Quantum Fluctuations
M. V. Feigel'man, A. I. Larkin, M. A. Skvortsov
The effect of Coulomb interaction upon superconductive proximity effect in disordered metals is studied, employing newly developed Keldysh functional approach (cond-mat/9907358). W…
Keldysh action for disordered superconductors
M. V. Feigel'man, A. I. Larkin, M. A. Skvortsov
Keldysh representation of the functional integral for the interacting electron system with disorder is used to derive microscopically an effective action for dirty superconductors.…
Andreev Spectroscopy for Superconductive Phase Qubit
M. V. Feigel'man, V. B. Geshkenbein, L. B. Ioffe +1
New method to probe quantum dynamics of the order parameter phase of a small superconductive island is proposed. The idea is to measure Andreev subgap conductance between the islan…
Quantum Glass Transition in a Periodic Long-Range Josephson Array
D. M. Kagan, L. B. Ioffe, M. V. Feigel'man
We show that the ground state of the periodic long range Josephson array frustrated by magnetic field is a glass for a sufficiently large Josephson energies despite the absence of…
