Potential curve for a Helium dimer confined by prolate spheroidal boxes
(2021-09-01)
Abstract: The potential curve for a confined He 2 dimer is computed using the variational method. The approach proposed here uses a trial function for the ground state composed of the Slater determinant with the orbitals ...
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 ...
Effects of quantum confinement on thermodynamic properties
(2021-02-01)
Abstract: Confined quantum systems can present anomalous behaviour. In particular, thermodynamic properties such as specific heat can show special features when the system is subject to spatial confinement described, for ...
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 ...
Comment on: “Harmonic oscillator in an elastic medium with a spiral dislocation”
(Elsevier, 2020-01-15)
We analyze recently derived eigenvalues of the Schrödinger equation for a harmonic oscillator in the presence of a spiral dislocation. We show that in the case of confinement those results do not take into account the limit ...
Shear viscosity of a model for confined granular media
(2014)
The shear viscosity in the dilute regime of a model for confined granular matter is studied by simulations and kinetic theory. The model consists on projecting into two dimensions the motion of vibrofluidized granular ...
Perturbation Theory for Confined Systems
(Springer, 2013-08-24)
We discuss the application of perturbation theory to a system of particles confined in a spherical box. A simple argument shows that the particles behave almost independently in sufficiently strong confinement. We choose ...
