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 ...

Entropies and IPR as Markers for a Phase Transition in a Two-Level Model for Atom–Diatomic Molecule Coexistence
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
A quantum phase transition (QPT) in a simple model that describes the coexistence of atoms and diatomic molecules is studied. The model, which is briefly discussed, presents a second-order ground state phase transition in ...

Describing resonances in a discrete basis
(American Physical Society, 2004-03-01)
The problem of describing resonances when the continuum is represented by a discrete set of normalizable states is addressed. In particular, here the description of resonances in a transformed harmonic oscillator basis is ...
