粒子数固定的小超导体的热力学
Thermodynamics of small superconductors with fixed particle number
摘要：
本文首次将投影变分法应用于描述固定粒子数小系统热力学的配对哈密顿量。自由能的最小化是通过熵的直接对角化来实现的。在有限温度下应用的投影后的变化提供了从很低到很高温度的奇数或偶数系统的精确正则性质的完美再现。
英文摘要：
The Variation After Projection approach is applied for the first time to the pairing hamiltonian to describe the thermodynamics of small systems with fixed particle number. The minimization of the free energy is made by a direct diagonalization of the entropy. The Variation After Projection applied at finite temperature provides a perfect reproduction of the exact canonical properties of odd or even systems from very low to high temperature.
