二维完全阻挫Josephson结阵列的非平衡态相变

Non-equilibrium Phase Transition of Two-dimensional Fully-frustrated Josephson Junction Arrays

在短时动力学标度方法的框架下,研究了二维完全阻挫Josephson结阵列在外加电流时的非平衡态相变-Ising型相变.采用电阻分流结动力学,分别求出了临界温度TC,静态临界指数2β/ν、ν和动态临界指数z.

The non-equilibrium phase transition, Ising-like phase transition of two-dimensional fully-frustrated Josephson junction arrays driven by external current was studied in the framework of the short-time dynamic scaling method. Within the resistively shunted junction （RSJ） dynamics, besides the critical temperature Tc, the static critical exponents 2β/v and v, and dynamic critical exponent z were obtained.
