主 题:nonlinear resonances hysteresis and jump phenomena modified Josephson junction
摘 要:In this paper,the equivalent circuit of the non-autonomous Josephson junction(JJ)is presented and the effect of the proper frequency on the phaseφis *** also study nonlinear resonance phenomena in the oscillations of a modified Josephson junction(MJJ).These oscillations are probed through a system of nonlinear differential equations and the multiple time scale method is employed to investigate all different types of resonance that *** results of primary,superharmonic and subharmonic resonances are obtained *** show that the system exhibits hardening and softening behaviors,as well as hysteresis and amplitude hopping phenomena in primary and superharmonic resonances,and only the hysteresis phenomenon in subharmonic *** addition,the stabilities and the steady state solutions in each type of resonances are kindly *** number of equilibrium points that evolve with time and their stabilities are also ***,the equations of motion are numerically integrated to check the correctness of analytical *** further show that the dynamics of the MJJ is strongly influenced by its parameters.
