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.
