The Yang-Lee zeros of the 1D Blume-Capel model on connected and non-connected rings
(Iop Publishing Ltd, 2005-08-05)
We carry out a numerical and analytic analysis of the Yang-Lee zeros of the ID Blume-Capel model with periodic boundary conditions and its generalization on Feynman diagrams for which we include sums over all connected and ...
Agent-based model to rural-urban migration analysis
(Elsevier B.V., 2006-05-15)
In this paper, we analyze the rural-urban migration phenomenon as it is usually observed in economies which are in the early stages of industrialization. The analysis is conducted by means of a statistical mechanics approach ...
Infrared finite solutions for the gluon propagator and the QCD vacuum energy
(1997-07-31)
Nonperturbative infrared finite solutions for the gluon polarization tensor have been found, and the possibility that gluons may have a dynamically generated mass is supported by recent Monte Carlo simulation on the lattice. ...
Formation of nano-crystalline structure at the interface in Cu–C composite
(Elsevier, 1999)
Formation of Cu–C composite is a difficult technological problem: carbon is practically insoluble in copper. We show that the heat treatment of the Cu–C composite leads to the formation of a thin (approximately 50 nm) ...
A multi-scale model for fluid transport through a bio-inspired passive valve
Tillandsia landbeckii is a rootless plant thriving in the hyper-arid Atacama Desert of Chile. These plants use unique cellulose-based microscopic structures called trichomes to collect fresh water from coastal fog. The ...
Free expansion of fermionic dark solitons in a boson-fermion mixture
(Iop Publishing Ltd, 2005-10-14)
We use a time-dependent dynamical mean-field-hydrodynamic model to study the formation of fermionic dark solitons in a trapped degenerate Fermi gas mixed with a Bose-Einstein condensate in a harmonic as well as a periodic ...
Can dissipation prevent explosive decomposition in high-energy heavy ion collisions?
(Elsevier B.V., 2005-05-19)
We discuss the role of dissipation in the explosive spinodal decomposition scenario of hadron production during the chiral transition after a high-energy heavy ion collision. We use a Langevin description inspired by ...
Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
(Springer, 2006-02-01)
We study the scaling of the S-3(1)-S-1(0) meson mass splitting and the pseudoscalar weak-decay constants with the mass of the meson, as seen in the available experimental data. We use an effective light-front QCD-inspired ...
Fermionic bright soliton in a boson-fermion mixture
(American Physical Soc, 2005-11-01)
We use a time-dependent dynamical mean-field-hydrodynamic model to study the formation of fermionic bright solitons in a trapped degenerate Fermi gas mixed with a Bose-Einstein condensate in a quasi-one-dimensional ...
Self-trapping of a binary Bose-Einstein condensate induced by interspecies interaction
(Iop Publishing Ltd, 2011-04-14)
The problem of self-trapping a Bose-Einstein condensate (BEC) and a binary BEC in an optical lattice (OL) and double well (DW) is studied using the mean-field Gross-Pitaevskii equation. For both DW and OL, permanent ...
