违反“细致平衡”标准的一种度量:离平衡“距离”的一种可能定义

A measure of the violation of the 'detailed balance' criterion: a possible definition of a 'distance' from equilibrium

T. Platini

摘要:

受R. K. P. Zia和B. Schmittmann,J. Stat. P07012(2007)中,我们提出通过概率流形成的矩阵的$p$ -范数($||K||_p$)来测量对“细致平衡”准则的违反。它的渐近分析,完全不对称的排斥过程,激发了一个“距离”的定义,从平衡$K^*$获得$p=1$。此外,我们表明,后者的数量和平均活动$A^*$都与熵产生的概率分布。最后,考虑到开放ASEP和开放ZRP,我们表明,粒子的电流给出了一个精确的措施违反“细致平衡”。

英文摘要:

Motivated by the classification of non-equilibrium steady states suggested by R.K.P. Zia and B. Schmittmann in J. Stat. Mech. P07012 (2007), we propose to measure the violation of the 'detailed balance' criterion by the $p$-norm ($||K||_p$) of the matrix formed by the probability currents. Its asymptotic analysis, for the totally asymmetric exclusion process, motivates the definition of a 'distance' from equilibrium $K^*$ obtained for $p=1$. In addition, we show that the latter quantity and the average activity $A^*$ are both related to the probability distribution of the entropy production. Finally, considering the open-ASEP and open-ZRP, we show that the current of particles gives an exact measure of the violation of 'detailed balance'.
