Content

We present the results of numerical study of the phase dynamics of the DC-SQUID with topologically trivial and nontrivial barriers. The current-voltage characteristics are calculated. The dependence of the return current and critical current on the magnitude of the magnetic field and on the ratio of current components (2π-periodic Cooper pairs and 4π-periodic Majorana fermions) is found. The qualitative behavior of this dependence is explained. In addition, the dependence of the reverse current and the critical current on the parameters βL and βc was calculated.
