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 ...

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 ...

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. ...

Excited state quantum phase transitions and chaos in the Dicke model
(American Institute of Physics, 2012)
In this contribution, the critical behavior of excited state quantum phase transitions (ESQPT's) and its relation to order and chaos in the Dicke model are studied. This model is nonintegrable. For comparison, the same ...

Stabilization method in two-body systems with core excitations
(American Institute of Physics, 2012)
The validity of the stabilization method in core+valence systems including the possibility of exciting the core is studied. A pseudostate method, based on the transformed harmonic oscillator basis, is extended to include ...
