Shape phase transitions in odd-A nuclei
(American Institute of Physics, 2008)
We investigate shape phase transitions in odd nuclei within the Interacting Boson Fermion Model. Special attention is given to the case of the transition from the vibrational behaviour to the stable axial deformation. ...

Decoherence and quantum quench: Their relationship with excited state quantum phase transitions
(American Institute of Physics, 2012)
We study the similarities and differences between the phenomena of Quantum Decoherence and Quantum Quench in presence of an Excited State Quantum Phase Transition (ESQPT). We analyze, on one hand, the decoherence induced ...

Core excitation effects in the breakup of halo nuclei
(American Institute of Physics, 2012)
The role of core excitation in the structure and dynamics of two-body halo nuclei is investigated. We present calculations for the resonant breakup of 11Be on protons at an incident energy of 63.7 MeV/nucleon, where core ...

Decoherence as a Signature of an Excited State Quantum Phase Transition in Two Level Boson Systems
(American Institute of Physics, 2009)
We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presence of quantum phase ...

A beyond mean-field study of the Tavis- Cummings model
(American Institute of Physics, 2019-09)
A beyond mean-field study of the Tavis-Cummings (TC) model is developed. This is the simplest model for describing the interaction of a radiation field with a system composed by an array of two-level atoms. The first ...

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 ...

Probing 6He structure from proton inelastic collisions
(American Institute of Physics, 2006)
We explore the Hyperspherical Harmonics pseudostate method to describe the 6He continuum. The method is use it within the multiple scattering of the transition amplitude (MST) approach to study inelastic scattering of p-6He ...

Core excitation effects in halo nuclei using a transformed oscillator basis
(American Institute of Physics, 2012)
A recent generalization of the Transformed Harmonic Oscillator basis, intended to consider core excitations in the structure of one nucleon halo nuclei, is applied to the break up of 11Be. The reaction studied is 11Be+208Pb ...

On the relation between E(5)- models and the interacting boson model
(American Institute of Physics, 2009)
The connections between the Ε(5)-models (the original Ε(5) using an infinite square well, Ε(5) - β4 Ε(5) - β6 and Ε(5) - β8), based on particular solutions of the geometrical Bohr Hamiltonian with γ -unstable potentials, ...

A beyond mean field study of Bose gases in a double-well potential with a Feshbach resonance
(American Institute of Physics, 2012)
The Bose-Hubbard model coupled to a Feshbach resonance is studied. Quantum phase transitions are analyzed within a beyond mean field framework in order to get finite size corrections to the simple mean field approach. ...
