Volume fluctuations and compressibility of a vibrated granular gas
(American Physical Society, 2010)
The volume fluctuations in the steady state reached by a vibrated granular gas of hard particles confined by a movable piston on the top are investigated by means of event-driven simulations. Also, a compressibility factor, ...

Coulomb breakup in a transformed harmonic oscillator basis
(American Physical Society, 2006-05-10)
The problem of Coulomb breakup in the scattering of a two-body loosely bound projectile by a heavy target is addressed. A basis of transformed harmonic oscillator (THO) wave functions is used to discretize the projectile ...

Transport coefficients for dense hard-disk systems
(American Physical Society, 2006)
A study of the transport coefficients of a system of elastic hard disks based on the use of Helfand-Einstein expressions is reported. The self-diffusion, the viscosity, and the heat conductivity are examined with averaging ...

Proton-proton correlations observed in two-proton decay of 19Mg and 16Ne
(The American Physical Society, 2008)
Proton-proton correlations were observed for the two-proton decays of the ground states of 19Mg and 16Ne. The trajectories of the respective decay products, 17Ne+p+p and 14O+p+p, were measured by using a tracking technique ...

Time-dependent aspects of the semiclassical approach in the analysis of heavy ion reactions
(American Physical Society, 2006-03-31)
The semiclassical approach is one of the fundamental tools used to investigate and analyze heavy ion reaction processes. We show in this contribution that the evolution of the motion that emerges from the knowledge of the ...

Continuous unitary transformations in two-level boson systems
(American Physical Society, 2005-12-01)
Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with O(2L+1) symmetry for large number ...

Study of the scattering of halo nuclei around the Coulomb barrier
(American Institute of Physics, 2011)
During the past ten years the present collaboration has carried out several experiments related with the study of radioactive nuclei. One of the topics in which we have centered our research, is the scattering of halo ...

Critical-point symmetries in Boson-Fermion systems: The case of shape transitions in odd nuclei in a multiorbit model
(American Physical Review, 2007-02-05)
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to γ-unstable behavior. In ...

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 ...

Scaling behavior and mechanism of formation of Si O2 thin films grown by plasma-enhanced chemical vapor deposition
(American Physical Society, 2007)
This paper reports a study of the kinetic roughening of Si O2 thin films prepared by plasma-enhanced chemical vapor deposition (PECVD). Tetramethylsilane has been used as a precursor, and the synthesis has been carried out ...
