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 ...

Four-body continuum-discretized coupled-channels calculations: Application to 6He+64Zn at 13.6 MeV
(American Institute of Physics, 2009)
The recently developed four-body continuum-discretized coupled-channels (CDCC) method, making use of the binning procedure [1], is applied to the reaction 6He+64Zn at 13.6 MeV (around the Coulomb barrier). Excellent agreement ...

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 ...

Scaling properties of the Lipkin model at the critical point
(American Institute of Physics, 2019)
The influence of Franco Iachello in Physics during the last 50 years and, in particular, in the use of algebraic methods applied to very different physical problems has been broad, extense and have permeated most branches ...

Shape phase transitions and critical points
(American Institute of Physics, 2009)
We investigate different aspects connected with shape phase transitions in nuclei and the possible occurrence of dynamical symmetries at the critical points. We discuss in particular the behaviour of the neighbour odd ...

Connection between decoherence and excited state quantum phase transitions
(American Institute of Physics, 2009)
In this work we explore the relationship between an excited state quantum phase transition (ESQPT) and the phenomenon of quantum decoherence. For this purpose, we study how the decoherence is affected by the presence of a ...
