无序非普适非平衡临界动力学

Non-universal non-equilibrium critical dynamics with disorder

M. D. Grynberg, G. L. Rossini, R. B. Stinchcombe

摘要:

我们研究有限尺寸标度方面的无序反应扩散过程在一维利用数值和分析方法。前者通过将其自由度加倍来平均相关演化算子的谱隙,而后者使用各种技术将运动方程映射到第一次通过时间过程。这两种方法是一致的非普遍的动态指数,并与拉伸指数标度形式的特定的无序实现。

英文摘要:

We investigate finite size scaling aspects of disorder reaction-diffusion processes in one dimension utilizing both numerical and analytical approaches. The former averages the spectrum gap of the associated evolution operators by doubling their degrees of freedom, while the latter uses various techniques to map the equations of motion to a first passage time process. Both approaches are consistent with nonuniversal dynamic exponents, and with stretched exponential scaling forms for particular disorder realizations.
