无Bogoliubov准粒子的随机相位近似

Random Phase Approximation without Bogoliubov Quasi-particles

L. Y. Jia

摘要:

本文提出了一种新的无规相位近似。该理论不是基于BCS/HFB基态的准粒子真空,而是基于文献[4]中确定的对凝聚。当前处理始终保持精确的粒子数。作为第一个测试的理论被认为是在两种特殊情况下:退化模型(大配对限制)和消失的配对限制。

英文摘要:

A new version of random phase approximation is proposed for low-energy harmonic vibrations in nuclei. The theory is not based on the quasi-particle vacuum of the BCS/HFB ground state, but on the pair condensate determined in Ref. [4]. The current treatment conserves the exact particle number all the time. As a first test the theory is considered in two special cases: the degenerate model (large pairing limit) and the vanished-pairing limit.
