Algebraic DVR Approaches Applied to Describe the Stark Effect
(MDPI, 2020)
Two algebraic approaches based on a discrete variable representation are introduced and applied to describe the Stark effect in the non-relativistic Hydrogen atom. One approach consists of considering an algebraic ...

U(5)-O(6) transition in the interacting boson model and the E(5) critical point symmetry
(American Physical Society, 2003-10-01)
The relation of the recently proposed E(5) critical point symmetry with the interacting boson model is investigated. The large-N limit of the interacting boson model at the critical point in the transition ...

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 ...

Intrinsic structure of two-phonon states in the interacting boson model
(Elsevier, 1998)
A general study of excitations up to two-phonon states is carried out using the intrinsicstate formalism of the Interacting Boson Model (IBM). Spectra and transitions for the different dynamical symmetries are analyzed and ...

Test of the proton-neutron interacting boson-fermion model in the region around A=190
(American Physical Society, 1986)
We present systematic calculations on nuclei in the region around A=190 within the framework of the proton-neutron interacting boson-fermion model. Energy levels and electromagnetic properties of both positive and negative ...

Hartree-Bose mean-field approximation for the interacting boson model (IBM-3)
(American Physical Society, 1998-02-01)
A Hartree-Bose mean-field approximation for the IBM-3 is presented. A Hartree-Bose transformation from spherical to deformed bosons with charge-dependent parameters is proposed which allows bosonic pair correlations and ...

Phase diagram of the proton-neutron interacting boson model
(American Physical Society, 2004-11-19)
We study the phase diagram of the proton-neutron interacting boson model with special emphasis on the phase transitions leading to triaxial phases. The existence of a new critical point between spherical and triaxial shapes ...
