摘要：
Critical regimes in the long Josephson junction (LJJ) are studied within the frame of a model accounting for the second harmonic in the current-phase relation (CPR). Numerical approach is shown to provide a good agreement with analytic predictions. Numerical results are presented to demonstrate the availabilities and advantages of the presented numerical scheme for investigation of bifurcations and properties of the magnetic flux distributions in dependence on the sign and value of the second harmonic in CPR.
