Уважаемые коллеги!
На заседании Ученого совета в пятницу 26 мая будет заслушан доклад:
А.С. Осин
*Second harmonics and anomalous Josephson effect in superconducting
multilayers*
In our work [1] we investigate the current-phase relation in a planar
diffuse tunnelling SIS′IS-junction in which the S′-layer contains in
addition a strong spin-orbit interaction and a Zeeman term. The
possibility of calculating the current-phase relation depending on the
phase jump of the order parameter at each boundary by perturbation
theory methods allows us to find the current dependence on the applied
magnetic field. Since taking into account the spin-orbit and Zeeman
terms leads effectively to the appearance of an additional contribution
to the vector potential, each harmonic of the current-phase relation is
shifted, which as a consequence leads to the anomalous Josephson effect
in this system.
[1] Second harmonics and anomalous Josephson effect in superconducting
multilayers, A. S. Osin, Alex Levchenko, and Maxim Khodas. In progress.
