Abstract: | 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. |
