How the Phase Slips in a Current-Biased Narrow Superconducting Stripe?
Yu. N. Ovchinnikov, A. A. Varlamov
The theory of current transport in a narrow superconducting channel accounting for thermal fluctuations is revisited. The value of voltage appearing in the sample is found as the f…
Low-Bias-Anomaly and Tunnel Fluctuoscopy
A. Glatz, A. A. Varlamov, V. M. Vinokur
Electron tunneling spectroscopy pioneered by Esaki and Giaever offered a powerful tool for studying electronic spectra and density of states (DOS) in superconductors. This led to i…
Mesoscopic variations of local density of states in disordered superconductors
A. E. Koshelev, A. A. Varlamov
We explore correlations of inhomogeneous local density of states (LDoS) for impure superconductors with different symmetries of the order parameter (s-wave and d-wave) and differen…
Fluctuoscopy of Disordered Two-Dimensional Superconductors
A. Glatz, A. A. Varlamov, V. M. Vinokur
We revise the long studied problem of fluctuation conductivity (FC) in disordered two-dimensional superconductors placed in a perpendicular magnetic field by finally deriving the c…
Theory of fluctuations in a two-band superconductor
A. E. Koshelev, A. A. Varlamov, V. M. Vinokur
A theory of fluctuations in two-band superconductor MgB is developed. Since the standard Ginzburg-Landau (GL) approach fails in description of its properties, we generalize i…
Strong vortex-antivortex fluctuations in the type II superconducting film
Yu. N. Ovchinnikov, A. A. Varlamov
The small size vortex-antivortex pairs proliferation in type II superconducting film is considered for the wide interval of temperatures below Tc. The corresponding contribution to…
