A microscopic theory of the magnetic-field modulation of critical currents is developed for plane Josephson junctions with anharmonic current-phase relations. The results obtained allow examining temperature-dependent deviations of the modulation from the conventional interference pattern. For tunneling through localized states in symmetric short junctions with a pronounced anharmonic behavior, the deviations are obtained and shown to depend on the distribution of channel transparencies.

Modeling of vortex dynamics in HTSs with defects under the impact of pulsed magnetic field
By means of the Monte Carlo method, a numerical study of the vortex system in a high-temperature superconductor under the impact of pulses of magnetic field has been conducted and low-tem temperature behavior of vortices and their penetration into samples have been shown to be independent of the pulse shape but strongly dependent of the type of pinning distribution.
Finite-size and shape effects on vortex configurations in superconducting isosceles right triangles
We numerically studied vortex configurations in superconducting isosceles right triangles. We found the solution of the London equation using Green’s function method. Then the Gibbs free energy for

The current-phase relation in Josephson junctions
This review provides a theoretical basis for understanding the current-phase relation (CPhiR) for the stationary (dc) Josephson effect in various types of superconducting junctions. The authors
0-pi Josephson tunnel junctions with ferromagnetic barrier.
The ground state of the 330 microm (1.3lambda(J)) long junction corresponds to a spontaneous vortex of supercurrent pinned at the 0-pi step and carrying approximately 6.7% of the magnetic flux quantum Phi(0).
Nonlocal supercurrent in mesoscopic Josephson junctions
We demonstrate that in a mesoscopic, fully phase coherent, superconductor–two-dimensional-electron-gas–superconductor structure the period of the critical current versus flux through the junction is
Universal distribution of transparencies in highly conductive Nb/AlO(x)/Nb junctions.
Experimental results for both the dc I-V curves at magnetic-field-suppressed supercurrent and the Josephson critical current in zero magnetic field coincide remarkably well with calculations based on the multimode theory of multiple Andreev reflections and the Schep-Bauer distribution.
