| Abstract(in English) | In this paper, we numerically calculated to investigate the possibility to generate chaos in the Josephson tehode. A bifurcation was observed from a limit cycle of the voltages to a quasi-periodic attractor when one of the normal resistances was decrease. With the decrease of the normal resistance, the quasi-periodic attractor finally broke down itself and chaotic oscillations appeared We also numerically calculated the maximal Lyapunov exponent has a positive value. Therefore we conclude that deterministic chaos is observed in the Josephson tetrode. A quasi-periodic attractor appears when the oscillation frequencies among Vl, V2,and V3 are irrational. When one of the parameters is changed, chaotic oscillation is suddenlyobserved at a certain value due to the strong nonlinear effect. |
