We propose a Hamiltonian-based approach to the nonextensive thermodynamics of small systems, where is a relative term comparing the size of the system to the size of the effective interaction region around it. We show that the effective Hamiltonian approach gives easy accessibility to the thermodynamic properties of systems strongly coupled to their surroundings. The theory does not rely on the classical concept of to characterize the system's interaction with the environment. Instead, it defines an effective interaction region over which a system exchanges extensive quantities with its surroundings, easily producing laws recently shown to be valid at the nanoscale.
我们提出了一种基于哈密顿量的方法来研究小系统的非广延热力学，其中 是一个相对项，用于比较系统大小与其周围有效相互作用区域的大小。我们表明，有效哈密顿量方法能轻松获取与周围环境强耦合系统的热力学性质。该理论不依赖于用经典的 概念来表征系统与环境的相互作用。相反，它定义了一个有效相互作用区域，系统在该区域内与其周围环境交换广延量，从而容易得出最近在纳米尺度上被证明有效的定律。
