Four-body continuum-discretized coupled-channels calculations
(The American Physical Society, 2009)
The development of a continuum-bin scheme of discretization for three-body projectiles is necessary for studies of reactions of Borromean nuclei such as He6 within the continuum-discretized coupled-channels approach. Such ...

Extended Analytical Solutions of the Bohr Hamiltonian with the Sextic Oscillator
(Institute of Physics Publishing, 2021)
Low-lying collective quadrupole states in even-even nuclei are studied for the particular case of a γ-unstable potential within the Bohr Hamiltonian. In particular, the quasi-exactly solvable β-sextic potential is extended ...

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 ...

Backbending of Dy isotopes described with the neutron-photon IBA plus two-quasiparticle model
(Elsevier, 1986)
The formalism of the neutron-photon interacting boson model, extended to include two-quasiparticle excitations, is used in a study of the high spin states of 154,156,158Dy isotropes. Good agreement is obtained between the ...

Continuum discretization using orthogonal polynomials
(American Physical Society, 2003)
A method for discretizing the continuum by using a transformed harmonic oscillator basis has recently been presented [Phys. Rev. A 63, 052111 (2001)]. In the present paper, we propose a generalization of that formalism ...

Decoherence as a signature of an excited-state quantum phase transition
(American Physical Society, 2008)
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 ...

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 ...

Exploring continuum structures with a pseudo-state basis
(The American Physical Society, 2010)
The ability of a recently developed square-integrable discrete basis to represent the properties of the continuum of a two-body system is investigated. The basis is obtained performing a simple analytic local scale ...
