An experimental study of the dependence on the current intensity of the erosion of thoriated tungsten cathodes in plasma arcs
(IEEE, 2001)The erosion occurring in thoriated tungsten cathodes used in transferred plasma torches operating with current intensities ranging from 30 to 210 A has been experimentally investigated. The cathode erosion rate was determined ... -
Role of Boson-Fermion Statistics on the Raman Spectra of Br2 X in Helium Clusters
(American Physical Society, 2004)The role played by the bosonic or fermionic character of He atoms surrounding a Br2 X molecule is analyzed through vibrotational Raman spectra simulations. Quantum chemistry-type calculations reveal the spin multiplicity ... -
Energies and density distributions of (4He)N clusters doped with Br2(X): a Hartree-like approach.
(American Physical Society, 2005)Energies and density distributions of the helium atoms in Br2sXd - s4HedN clusters are calculated using a quantum “Hartree-like” approach in which the dopant molecule and the 4He atoms play the role of the nuclei and ... -
Accesibilidad a Internet: requisitos para la calidad en la docencia e investigación
(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2005)A good Internet platform for teaching and research must be accessible, independently of the computer platform used, language and other peculiarities (personal or external). This work analyzes the current limitations of ... -
Polar di-halogen molecules solvated in bosonic helium clusters: The paradigm of ICl(X)
(American Physical Society, 2006)Energies and structures of 4HeN-ICl(X) complexes, N<=30, are determined within the framework of a recently developed Hartree-like approach [Phys. Rev. A 71, 033203 (2005)], in which the He atoms play the role of the ... -

ASPIN: An all spin scattering code for atom–molecule rovibrationally inelastic cross sections
(Elsevier, 2008)We present in this work a new computational code for the quantum calculation of integral cross sections for atom–molecule (linear) scattering processes. The atom is taken to be structureless while the molecule can be in ... -
LiH−(X2Σ+)+3,4He rotational quenching at ultralow energies: spin-flip and isotopic effects from quantum dynamics on an ionic system
(Springer, 2009)We study in this work the quantum scattering between a helium atom and a LiH− molecule at low and ultralow energies. For the noble gas we have considered the two natural isotopes 3He, 4He, plus a “mock” 3.5He. Our aim ... -
Spin-driven structural effects in alkali doped 4He clusters from quantum calculations
(American Institute of Physics, 2009)In this paper, we carry out variational Monte Carlo and diffusion Monte Carlo (DMC) calculations for Li2(1Sigma)(4He)N and Li2(3Sigma)(4He)N with N up to 30 and discuss in detail the results of our computations. After a ... -

Modulational instability in two cubic–quintic Ginzburg–Landau equations coupled with a cross phase modulation term
(Elsevier, 2010)Modulation instability is investigated in two cubic–quintic Ginzburg–Landau equations coupled with a cross phase modulation type term. After carrying out a stability analysis an expression for gain is ob tained. Some ... -
Simulations of pulse propagation in optical fibers using graphics processor units
(Elsevier, 2011)Several simple cases of pulse propagation in optical fibers have been simulated using a graphics processor unit. Comparisons with simulations in a computer processor unit are also reported. Speedups from 4 to 36 have been ... -
Stationary pulses in two cubic–quintic Ginzburg–Landau equations coupled with a cross phase modulation term
(Elsevier, 2011)Existence of stationary pulses are investigated in system modelled by two cubic–quintic Ginzburg–Landau equations coupled with a cross phase modulation term. Only for the symmetric case, that is, when the two components ... -
Quantum Features of a Barely Bound Molecular Dopant: Cs2(3Σu) in Bosonic Helium Droplets of Variable Size
(American Chemical Society, 2011)We present in this work the study of small 4HeN-Cs2(3Σu) aggregates (2 <= N <= 30) through combined variational, diffusion Monte Carlo (DMC), and path integral Monte Carlo (PIMC) calculations. The full surface is modeled ... -
Diffusion Monte Carlo description of Cs2–(4He)N clusters: an example of weak dopant–helium interaction
(Institute of Physics, 2011)In this paper, we study the energy and geometric properties of Cs2–(4He)N clusters, 2 <= N <= 20, N even, through a diffusion Monte Carlo methodology. Considering the results for doped clusters in which the He–impurity ... -
