Mean-field description of high-spin states
TL;DR: Recently, high-spin observations reveal entirely new modes of collective rotational motion and the existence of novel symmetries and spontaneous symmetry breaking phenomena, uncovering hitherto unexploited coupling schemes of intrinsic and collective degrees of freedom.
Journal ArticleDOI
Coherent and chaotic properties of nuclear pairing
TL;DR: In this article, the properties of pairing interaction in the shell model framework are considered with the aid of an exact numerical solution utilizing the quasispin symmetry, emphasizing the features which are out of reach for the usual approximate techniques based on BCS approach supplemented by the random phase approximation treatment of pair vibrations, especially in the region of weak pairing where the BCS plus random-phase approximation theory fails.

The 0+ states in doubly even deformed nuclei
TL;DR: In this paper, the Kπ = 0+ states in deformed rare-earth nuclei are calculated within the pairing plus multipole-multipole interaction model with the quadrupole-quadrupole one.
Journal ArticleDOI
Self-consistent pairing and anomalous properties of the monopole states in deformed nuclei
TL;DR: In this article, the existence of states in the excitation spectra of nuclei with anomalously large values of the parameter X is explained in the framework of a model with self-consistent pairing.

Coupled Electron-Phonon System
TL;DR: In this article, a coupled electron-phonon system is considered for phonon spectra of Einstein and Debye forms, and the single-particle electron Green's function $G$ is calculated in a nonperturbative manner in both models, and its spectral weight function is examined to determine the validity of a quasiparticle picture.

Time-dependent self-consistent field and collective nuclear Hamiltonian
TL;DR: In this paper, an expression for the collective Hamiltonian H c was obtained proceeding from general “microscopic” concepts; no induced excitation devices characteristic of the cranking model are used.
