Transport in a One-Dimensional Superfluid: Quantum Nucleation of Phase Slips
H. P. Büchler, V. B. Geshkenbein, G. Blatter
We present an analytical derivation for the quantum decay rate of the superflow through a weak link in a one-dimensional Bose-Einstein-condensate. The effective action for the phas…
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…
Supercurrent Quantization in Narrow Channel SNS Junctions
Nikolai M. Chtchelkatchev, Gordey B. Lesovik, Gianni Blatter
We determine the quasi-particle excitation spectrum in the normal region of a narrow ballistic superconductor--normal-metal--superconductor (SNS) Josephson contact. Increasing the…
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…
Defect-Unbinding Transition in Layered Superconductors
Matthew J. W. Dodgson, Vadim B. Geshkenbein, Gianni Blatter
We establish a new interstitial-vacancy unbinding transition of the Berezinskii-Kosterlitz-Thouless type, transforming the three dimensional pancake vortex lattice of a decoupled l…
Nonlocality in mesoscopic Josephson junctions with strip geometry
Urs Ledermann, Alban L. Fauchere, Gianni Blatter
We study the current in a clean superconductor-normal-metal-superconductor junction of length d and width w in the presence of an applied magnetic field H. We show that both the ge…
