Theoretical Results

We report on recent progress in the description of shape transitions in atomic nuclei. The main experimental signatures are mentioned along with basic theoretical models describing the critical character of the nuclear shape evolution. We then discuss some new theoretical results obtained within the framework of the interacting boson model and related approaches. It is argued that these models can be used to probe some fundamental aspects of quantum phase transitions.

Exactly Solvable

We employ two different Lipkin-like, exactly solvable models so as to display features of the competition between different fermion–fermion quantum interactions (at finite temperatures). One of our two interactions mimics the pairing interaction responsible for superconductivity. The other interaction is a monopole one that resembles the so-called quadrupole one, much used in nuclear physics as a residual interaction. The pairing versus monopole effects here observed afford for some interesting insights into the intricacies of the quantum many body problem, in particular with regards to so-called quantum phase transitions (strictly, level crossings).
