Novel results from an algebraic approach to molecular bending dynamics
(Institute of Physics Publishing, 2011)
We present a brief review of research topics of current interest that depend on an algebraic approach to molecular bending dynamics. This approach is based on a u(3) spectrum generating algebra. In particular, we briefly ...

Quantum phase transitions of atom-molecule Bose mixtures in a double-well potential
(2014)
The ground state and spectral properties of Bose gases in double-well potentials are studied in two different scenarios: (i) an interacting atomic Bose gas, and (ii) a mixture of an atomic gas interacting with diatomic ...

Odd-even 147–153Pm isotopes within the neutron-proton interacting boson-fermion model
(American Physical Society, 2011)
Low-lying energy states of the 147 -153Pm isotopic chain are studied within the framework of the neutron-proton interacting boson-fermion model (IBFM-2). The spectra of these isotopes show a transition from a particle ...

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 ...

Be 9 + Sn 120 scattering at near-barrier energies within a four-body model
(American Physical Society, 2018)
Cross sections for elastic and inelastic scattering of the weakly bound Be9 nucleus on a Sn120 target have been measured at seven bombarding energies around and above the Coulomb barrier. The elastic angular distributions ...

Weakly-bound three-body nuclear systems: structure, reactions and astrophysical implications
(2016-05-11)
Esta memoria de tesis surge con la idea de estudiar sistemas nucleares de interés astrofísico.La comprensión de los procesos de nucleosíntesis requiere una conexión profunda entre física nuclear y astrofísica. En general, ...

Continuum-discretized coupled-channels calculations with core excitation
(American Physical Society, 2014)
The effect of core excitation in the elastic scattering and breakup of a two-body halo nucleus on a stable target nucleus is studied. The structure of the weakly bound projectile is described in the weak-coupling limit, ...

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 ...

Excited-state quantum phase transitions in a two-fluid Lipkin model
(American Physical Society, 2017-05-30)
Background: Composed systems have become of great interest in the framework of ground-state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems, the study ...
