有限温度BCS理论中的重整势

Rearrangement potential in Finite Temperature BCS Theory

若粒子间有效相互作用明显地密度相关，则对热力学势采用变分原理后可以发现，有限温度的ＢＣＳ能隙方程中包含了一个额外的项——重整势ｕＤ。

We study the finite-temperature BCS gap eguations for a system where the inter-particle effective interaction is explicitly density dependent.Starting from a variational principle for the thermodynamic potential,these equations are found to contain an extra term_the rearrargement potential u D.A general expression for u D is derived.Using an effective Gogny interaction, the formalism is applied to a superconductivity/superfluidity calculation of symmetric nuclear matter.
