*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.

multilayers, A. S. Osin, Alex Levchenko, and Maxim Khodas. In progress.
