边界诱导非平衡相变到吸收态

Boundary-induced nonequilibrium phase transition into an absorbing state

A. C. Barato, H. Hinrichsen

摘要:

我们证明了一维吸收相变可能是由一个单一的网站的动力学。作为一个例子,我们考虑扩散粒子的一维模型,其中在边界处的单个站点根据接触过程的动力学而演变。由于在这个网站上的后代生产率是不同的,该模型表现出一个相变从一个波动的活性相到一个吸收状态。通过数值模拟和近似技术,分析了过渡的普遍性质。

英文摘要:

We demonstrate that absorbing phase transitions in one dimension may be induced by the dynamics of a single site. As an example we consider a one-dimensional model of diffusing particles, where a single site at the boundary evolves according to the dynamics of a contact process. As the rate for offspring production at this site is varied, the model exhibits a phase transition from a fluctuating active phase into an absorbing state. The universal properties of the transition are analyzed by numerical simulations and approximation techniques.
