Tsallis熵的性质与熵增加原理

Property of Tsallis entropy and principle of entropy increase

Jiulin Du

摘要:

考察了两个不同温度的系统相互接触并达到热平衡时Tsallis熵的性质。证明了两个系统接触后的总Tsallis熵不会减小。在这样的例子中,我们导出了Tsallis熵变化的一个不等式,从而在非广延统计力学的框架下推广了熵增加原理.

英文摘要:

The property of Tsallis entropy is examined when considering tow systems with different temperatures to be in contact with each other and to reach the thermal equilibrium. It is verified that the total Tsallis entropy of the two systems cannot decrease after the contact of the systems. We derived an inequality for the change of Tsallis entropy in such an example, which leads to a generalization of the principle of entropy increase in the framework of nonextensive statistical mechanics.
