Remarks on shape phase transitions in nuclei
(Institute of Physics Publishing, 2009)
Various aspects of shape phase transitions in even as well as odd systems are reviewed. Firstly, the case of an odd j 3/2 particle coupled to an even-even boson core that undergoes a transition from spherical limit (U(5)) ...

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 ...

Finite-size scaling exponents in the interacting boson model
(American Physical Society, 2005-07-01)
We investigate the finite-size scaling exponents for the critical point at the shape-phase transition from U(5) (spherical) to O(6) (deformed γ-unstable) dynamical symmetries of the interacting boson model, making use of ...

Continuum discretization in a basis of transformed harmonic-oscillator states
(American Physical Society, 2001)
The method of defining a transformed harmonic-oscillator (THO) basis, designed to take an account of continuum, by an appropriate discretization is discussed. This method is applied to two analytical one-dimensional ...

Consistent baryon mapping of quark systems
(American Physical Society, 1994)
We present a new and consistent mapping of colorless three-quark clusters onto colorless triplet fermions (baryons) and test it in the context of a three-color extension of the Lipkin model. For systems with two triplets ...

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 ...

Configuration localized wave functions: General formalism and applications to vibrational spectroscopy of diatomic molecules
(American Physical Society, 2000)
A general formalism for constructing configuration localized states for one-dimensional potentials is presented. It allows the evaluation of accurate approximations to the vibrational matrix elements of the momentum operator ...
