原子核结构理论中的热Bogoliubov变换

Thermal Bogoliubov transformation in nuclear structure theory

A. I. Vdovin, Alan A. Dzhioev

摘要:

热Bogoliubov变换是H.梅泽和同事。本文提出了一种研究热核性质的方法,它是基于将著名的准粒子-声子模型推广到有限温度的TFD形式。QPM-TFD组合的一个显著特征是有可能超越标准近似,如热Hartree-Fock或热RPA近似。

英文摘要:

Thermal Bogoliubov transformation is an essential ingredient of the thermo field dynamics -- the real time formalism in quantum field and many-body theories at finite temperatures developed by H. Umezawa and coworkers. The approach to study properties of hot nuclei which is based on the extension of the well-known Quasiparticle-Phonon Model to finite temperatures employing the TFD formalism is presented. A distinctive feature of the QPM-TFD combination is a possibility to go beyond the standard approximations like the thermal Hartree-Fock or the thermal RPA ones.
