非广延形式的Klimontovich S定理与约束问题

Klimontovich`s S theorem in nonextensive formalism and the problem of constraints

G. B. Bagci

摘要:

普通玻尔兹曼-吉布斯熵不足以用于依赖于产生不同平均能量值的控制参数的系统。这样的系统不能给出非平衡熵值和平衡熵值之间的正确比较。Klimontovich的S定理通过能量重整化和利用护送分布解决了这个问题。由于非广延热统计学是玻尔兹曼-吉布斯熵的推广,它也表现出同样的缺陷。为了弥补这一点,我们提出了Klimontovich的S定理的非广延推广。我们表明,这种推广需要使用普通概率和相关的相对熵,除了重整化的能量。最后,我们证明了Van der Pol振子的广义S定理。

英文摘要:

Ordinary Boltzmann-Gibbs entropy is inadequate to be used in systems depending on a control parameter that yield different mean energy values. Such systems fail to give the correct comparison between the off-equilibrium and equilibrium entropy values. Klimontovich's S theorem solves this problem by renormalizing energy and making use of escort distributions. Since nonextensive thermostatistics is a generalization of Boltzmann-Gibbs entropy, it too exhibits this same deficiency. In order to remedy this, we present the nonextensive generalization of Klimontovich's S theorem. We show that this generalization requires the use of ordinary probability and the associated relative entropy in addition to the renormalization of energy. Lastly, we illustrate the generalized S theorem for the Van der Pol oscillator.
