Chiral symmetry, massive gluons and confinement
(2013-04-24)
It is quite difficult to obtain non-trivial chiral symmetry breaking solutions for the quark gap equation in the presence of dynamically generated gluon masses. An effective confining propagator has recently been proposed ...
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 ...

Quantum confinement in hydrogen bond
(Wiley-Blackwell, 2015-06-15)
In this work, the quantum confinement effect is proposed as the cause of the displacement of the vibrational spectrum of molecular groups that involve hydrogen bonds. In this approach, the hydrogen bond imposes a space ...
QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons
(Elsevier B.V., 2015-05-11)
Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is ...
Response to: Comment on The effect of confinement on the electronic energy and polarizability of a hydrogen molecular ion'
(Wiley-Blackwell, 2016-12-01)
In this reply we clarify questions point out in the Comment on: The Effect of Confinement on the Electronic Energy and Polarizability of a Hydrogen Molecular Ion by J. F. da Silva, F. R. Silva and E. Drigo Filho, Int. J. ...
The effect of confinement on the electronic energy and polarizability of a hydrogen molecular ion
(Wiley-Blackwell, 2016-04-05)
The electronic energy and the polarizability of a confined hydrogen molecular ion in the ground state and the first excited state, for cavities of different volumes, are calculated using the variational method. In the ...

Excited states for hydrogen ion molecule confined by a prolate spheroidal boxes: variational approach
(2020-08-01)
The energy eigenvalues for confined H2+ molecule are computed by using the variational method. The approach proposed here uses a trial molecular function for the ground state composed of a linear combination of atomic ...
