Phase diagram for a cubic-Q interacting boson model Hamiltonian: Signs of triaxiality
(American Physical Society, 2011)
An extension of the Interacting Boson Model that includes the cubic (QI×QI×Q I)(0) term is proposed. The potential energy surface for the cubic quadrupole interaction is explicitly calculated within the coherent state ...

Quantum phase transitions in odd-A nuclei: The effect of the odd particle from spherical to oblate shapes
(Institute of Physics Publishing, 2015)
Quantum shape-phase transitions in odd-nuclei are investigated within the framework of the interacting boson-fermion model (IBFM). We consider the case of a single-j fermion coupled to an even-even boson core that performs ...

Quantum shape phase transitions from spherical to deformed for Bose-Fermi systems: the effect of the odd particle around the critical point
(EDP sciences, 2014)
Quantum phase transitions in odd-nuclei are investigated within the framework of the interacting boson-fermion model with a description based on the concept of intrinsic states. We consider the case of a single j=9/2 ...

Review of critical point symmetries and shape phasetransitions within algebraic and collective models
(2012)
Several aspect of shape phase transitions and critical point symmstries are reviewed inthis contribution within the frameworks of the Interacting Boson Model(IBM) and theInteracting Boson Fermion Model(IBFM) for even ...

Shape phase transition in odd-even nuclei: From spherical to deformed γ -unstable shapes
(The American Physical Society, 2010)
Shape phase transitions in odd-A nuclei are investigated within the framework of the interacting boson-fermion model. The case of a single j=9/2 fermion coupled to an even-even boson core is considered. This boson core ...
