Ladder operators for subtle hidden shape invariant potentials
Elso Drigo Filho, Regina Maria Ricotta
Ladder operators can be constructed for all potentials that present the integrability condition known as shape invariance, satisfied by most of the exactly solvable potentials. Usi…
Supersymmetric variational energies of 3d confined potentials
Elso Drigo Filho, Regina Maria Ricotta
Within the approach of Supersymmetric Quantum Mechanics associated with the variational method a recipe to construct the superpotential of three dimensional confined potentials in…
Supersymmetric variational energies for the confined Coulomb system
Elso Drigo Filho, Regina Maria Ricotta
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.
Induced Variational Method from Supersymmetric Quantum Mechanics and the Screened Coulomb Potential
Elso Drigo Filho, Regina Maria Ricotta
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 approa…
Morse potential energy spectra through the variational method and supersymmetry
Elso Drigo Filho, Regina Maria Ricotta
The Variational Method is applied within the context of Supersymmetric Quantum Mechanics to provide information about the energy and eigenfunction of the lowest levels of a Hamilto…
The Hierarchy of Hamiltonians for a Restricted Class of Natanzon Potentials
Elso Drigo Filho, Regina Maria Ricotta
The restricted class of Natanzon potentials with two free parameters is studied within the context of Supersymmetric Quantum Mechanics. The hierarchy of Hamiltonians is indicated,…
Supersymmetry, Variational Method and Hulthén Potential
Elso Drigo Filho, Regina Maria Ricotta
The formalism of Supersymmetric Quantum Mechanics provides us the eigenfunctions to be used in the variational mathod to obtain the eigenvalues for the Hulthén Potential.
