Report

Possibility of superconducting gap increase in heterogeneous superconductors

Autor: Zhilyaev, I. N.

A picture of pair scattering on Wigner crystal islands for the earlier proposed superconducting state in BCS superconductor with characteristic HTSC properties is presented. The model is supposed to be valid for thin heterogeneous films and boundarie

Report

A possibility of increase of a superconducting gap in two-dimensional BCS superconductor

Autor: Zhilyaev, I. N.

According to the BCS model the probability of filling of pair electron states vk2 as a function of kinetic energy is smeared i.e. is not a step function. This means that part of energy of connection through virtual phonons is consumed to increase the

Report

A possibility of kinetic energy economy at the transition of two-dimensional conductor to the superconducting state

Autor: Zhilyaev, I. N.

For a two-dimensional conductor under the conditions of the Bardeen-Cooper-Schrieffer mechanism of superconductivity, a factor resulting in economy in kinetic energy upon the transition to the superconducting state and connected to the zero oscillati

Induction of dc voltage, proportional to the persistent current, by external ac current on system of inhomogeneous superconducting loops

Autor: Dubonos, S. V., Kuznetsov, V. I., Zhilyaev, I. N., Nikulov, A. V., Firsov, A. A.

Publikováno v: JETP Lett. v.77, p.371-375, (2003)

A dc voltage induced by an external ac current is observed in system of asymmetric mesoscopic superconducting loops. The value and sign of this dc voltage, like the one of the persistent current, depend in a periodical way on a magnetic field with pe

Report

The Little-Parks effect in an inhomogeneous superconducting ring

Autor: Nikulov, A. V., Zhilyaev, I. N.

Publikováno v: Journal of Low Temperature Physics vol.112, Nos.3/4, August 1998, pp.227-295

An inhomogeneous superconducting ring placed in a magnetic field is considered. It is shown that the superconducting transition of the section with lowest critical temperature may be a first order phase transition if the magnetic flux contained withi
