Supersymmetric variational energies for the confined Coulomb system
(Elsevier B.V., 2002-07-01)
The methodology based on the association of the variational method with supersymmetric quantum mechanics is used to evaluate the energy states of the confined hydrogen atom. (C) 2002 Elsevier B.V. B.V. All rights reserved.
Chiral symmetry breaking in QCD-like gauge theories with a confining propagator and dynamical gauge boson mass generation
(Academic Press Inc. Elsevier B.V., 2012-04-01)
We study chiral symmetry breaking in QCD-like gauge theories introducing a confining effective propagator, as proposed recently by Cornwall, and considering the effect of dynamical gauge boson mass generation. The effective ...
Electronegativity under confinement
(MDPI, 2021)
The electronegativity concept was first formulated by Pauling in the first half of the 20th century to explain quantitatively the properties of chemical bonds between different types of atoms. Today, it is widely known ...
Confined Lennard-Jones potential: a variational treatment
(World Scientific Publ Co Pte Ltd, 2010-03-14)
In this work, the energy eigenvalues for the confined Lennard-Jones potential are calculated through the Variational Method allied to the Super symmetric Quantum Mechanics. Numerical results are obtained for different ...
Multivacuum states in a fermionic gap equation with massive gluons and confinement
(World Scientific Publ Co Pte Ltd, 2015-05-10)
We study the nontrivial solutions of the Quantum Chromodynamics (QCD) fermionic gap equation (FGE) including the contribution of dynamically massive gluons and the confining propagator proposed by Cornwall. Without the ...
Ground-state energy for confined H2: a variational approach
(2018-05-01)
Ground-state energies for confined H2 molecule are computed using the variational method. The approach proposed here uses a molecular wave function of the valence bond type, written as the sum of the covalent term and the ...
Fluids confined in wedges and by edges: Virial series for the line-thermodynamic properties of hard spheres
(American Institute of Physics, 2014-12)
This work is devoted to analyze the relation between the thermodynamic properties of a confined fluid and the shape of its confining vessel. Recently, new insights in this topic were found through the study of cluster ...
Comparison of free range broiler chicken strains raised in confined or semi-confined systems
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2005-06)
The present study was carried out to compare the growth curve, performance and carcass yield of two broiler strains, Paraíso Pedrês (PP) and ISA Label (ISA), raised in confined or semi-confined systems. It was used a ...
Economic evaluation of the termination of beef cattle from pasture, semi-confined or in confinement with high grain diet
(Univ Fed Rural Pernambuco, Dept Administracao, 2019-04-01)
Supersymmetric variational energies of 3d confined potentials
(Elsevier B.V., 2003-12-29)
Within the approach of supersymmetric quantum mechanics associated with the variational method a recipe to construct the superpotential of three-dimensional confined potentials in general is proposed. To illustrate the ...
