钱敏 %A 王家赠 %J 中国物理快报 %D 2007 %I %X The dynamics of the dc and ac driving Josephson junction equation is studied in terms of the two-dimensional Poincaré map. The smooth invariant circle on the phase cylinder in over-damped case a ) 2 loses smoothness as a decreases and becomes a strange attractor eventually. This triggers two kinds of chaos, one occurs in the regions between two Arnold tongues and the other occurs within the tongues. %K 05 %K 45 %K Pq %K 05 %K 45 %K Ac %K 74 %K 50 %K +r
