超导隧道结稳定时间研究

he stabilization time is from the initial to the stable state. Resistively-capacitance-inductively-shunted model (RCLSJ) was used to study the nonlinear dynamical behavior of Josephson tunnel junction (JJ). The stabilization time of JJs is calculated by the information of voltage waveform. With certain irradiation, four-dimensional image of stabilization time of Josephson tunnel junctions is calculated in the three-dimensional parameter space composed of the junction capacitance C, shunt inductance L, and the bias current I. This method which uses statistical methods to contrast stabilization time of RCLSJ model under different parameters and working conditions will be used. This article firstly simulated the relation between average stabilization time and initial conditions that have a great influence on chaos state, then calculated the average stabilization time under different irradiation frequencies and intensity. The results show the average stabilization time is regular. These data can improve efficiency of experiment and simulation.
