Relation between E(5) models and the interacting boson model
(The American Physical Society, 2008)
The connections between the E(5) models [the original E(5) using an infinite square well, E(5)-β4, E(5)-β6, and E(5)-β8], based on particular solutions of the geometrical Bohr Hamiltonian with γ-unstable potentials, and ...

Four-body continuum-discretized coupled-channels calculations using a transformed harmonic oscillator basis
(The American Physical Society, 2008)
The scattering of a weakly bound three-body system by a target is discussed. A transformed harmonic oscillator basis is used to provide an appropriate discrete and finite basis for treating the continuum part of the spectrum ...

Forced synchronization of a quantum dissipative dynamics
(American Institute of Physics, 2007)
We generalize the phenomenon of forced stochastic synchronization into the quantum domain within the framework of a paradigmatic spin-boson model (tunneling charge, or flipping spin 1/2 coupled to an environment) which ...

Hydrodynamic character of the nonequipartition of kinetic energy in binary granular gases
(American Physical Society, 2009)
The influence of the heating mechanism on the kinetic energy densities of the components of a vibrated granular mixture is investigated. Collisions of the particles with the vibrating wall are inelastic and characterized ...

Analysis of the elastic scattering measured with a 23.7 MeV 7Be beam on a 9Be target.
(American Institute of Physics, 2009)
We present new data for the reaction 7Be+9Be measured at Elab =23.7 MeV. The elastic scattering angular distribution has been analyzed using the phenomenological optical model and the coupled-channels method. In the ...

Superscaling and neutral current quasielastic neutrino-nucleus scattering beyond the relativistic Fermi gas model
(The American Physical Society, 2007)
The superscaling analysis is extended to include quasielastic (QE) scattering via the weak neutral current (NC) of neutrinos and antineutrinos from nuclei. The scaling function obtained within the coherent density fluctuation ...

Mesoscopic theory of critical fluctuations in isolated granular gases
(American Physical Review, 2006-05-12)
Fluctuating hydrodynamics is used to describe the total energy fluctuations of a freely evolving gas of inelastic hard spheres near the threshold of the clustering instability. They are shown to be governed only by vorticity ...

One-particle spectroscopic intensities as a signature of shape phase transition: The γ -unstable case
(American Physical Society, 2006-08-09)
We investigate the evolution of one-particle spectroscopic intensities as a possible signature of shape phase transitions. The study describes the odd systems in terms of the interacting boson–fermion model. We consider ...

Shear state of freely evolving granular gases
(American Physical Society, 2008)
Hydrodynamic equations are used to identify the final state reached by a freely evolving granular gas above but close to its shear instability. The theory predicts the formation of a two bands shear state with a steady density ...

Breakdown of the fluctuation-dissipation relations in granular gases
(IOP Publishing Ltd., 2008-10)
A numerical molecular dynamics experiment measuring the two-time correlation function of the transversal velocity field in the homogeneous cooling state of a granular gas modeled as an ensemble of inelastic hard particles ...
