Signatures of criticality in the evolution of the nuclear ground-state shapes across the N× Z
plane are discussed. Attention is paid to specific data indicating sudden structural changes …

This review is focused on various properties of quantum phase transitions (QPTs) in the
Interacting Boson Model (IBM) of nuclear structure. The model describes collective modes of …

Here we discuss the theory and analyze in detail the guidance properties of linear arrays of
metamaterial/plasmonic small particles as nanoscale optical nanotransmission lines …

Recently, the idea of quantum phase transitions has been applied to equilibrium shape
changes in finite atomic nuclei. An introduction to and discussion of this concept, both from …

The properties of even-even nuclei with 30⩽ Z⩽ 82, A⩾ 60 have been examined to find
examples displaying the characteristics of E (5) critical-point behavior for the shape …

The Bohr Hamiltonian, also called collective Hamiltonian, is one of the cornerstones of
nuclear physics and a wealth of solutions (analytic or approximated) of the associated …

The experimental energy staggering in γ bands of rare earths and actinides exhibits three
distinct patterns as a function of angular momentum that are typical of well-deformed …

Abstract Quantum Phase Transitions arising in algebraic and collective models of nuclear
structure are reviewed. The concept of quantum phases and phase transitions is described …

A unified presentation of the quasi-exact solutions of the Bohr Hamiltonian with a sextic
oscillator potential is offered by evidencing the similarities and the differences between …

Relativistic mean field theory with the NL3 force is used to produce potential energy surfaces
(PESs) for a series of isotopes suggested as exhibiting critical point symmetries. Relatively …
