非广延热统计学框架下的强度变量

Intensive variables in the framework of the non-extensive thermostatistics

A. M. Scarfone

摘要:

通过假设由相同的非广延熵所支配的两个系统之间的适当的能量合成定律,我们重新审视了温度和压力的定义,从热力学第零原理产生的,以与理论的热统计结构一致的方式。我们表明,这些量的定义是敏感的熵和内能管理系统的组成定律。通过这种方式,我们可以澄清在非广延统计力学的背景下可能引入密集变量所提出的一些问题。

英文摘要:

By assuming an appropriate energy composition law between two systems governed by the same non-extensive entropy, we revisit the definitions of temperature and pressure, arising from the zeroth principle of thermodynamics, in a manner consistent with the thermostatistics structure of the theory. We show that the definitions of these quantities are sensitive to the composition law of entropy and internal energy governing the system. In this way, we can clarify some questions raised about the possible introduction of intensive variables in the context of non-extensive statistical mechanics.
