Supersymmetry, Variational Method and Hulth\'en Potential
The formalism of Supersymmetric Quantum Mechanics provides us the
eigenfunctions to be used in the variational mathod to obtain the eigenvalues
for the Hulth\'en Potential.Comment: 5 pages, LateX file, to appear in Modern Physics Letters
Induced Variational Method from Supersymmetric Quantum Mechanics and the Screened Coulomb Potential
The formalism of Supersymmetric Quantum Mechanics supplies a trial wave
function to be used in the Variational Method. The screened Coulomb potential
is analysed within this approach. Numerical and exact results for energy
eigenvalues are compared.Comment: 7 pages, LATE
Quantum Confinement in Hydrogen Bond of DNA and RNA
The hydrogen bond is a fundamental ingredient to stabilize the DNA and RNA
macromolecules. The main contribution of this work is to describe
quantitatively this interaction as a consequence of the quantum confinement of
the hydrogen. The results for the free and confined system are compared with
experimental data. The formalism to compute the energy gap of the vibration
motion used to identify the spectrum lines is the Variational Method allied to
Supersymmetric Quantum Mechanics.Comment: 8 pages, 3 figures. To appear in The Proceedings of the 30th
