The energy states of quantum dots through the variational method and SQM
Elso Drigo Filho, Regina Maria Ricotta
The Variational Method is applied within the context of Supersymmetric Quantum Mechanics to provide information about the energy states of a hydrogenic donor in a quantum dot.
A new exactly solvable Eckart-type potential
Elso Drigo Filho, Regina Maria Ricotta
A new exact analytically solvable Eckart-type potential is presented, a generalisation of the Hulthen potential. The study through Supersymmetric Quantum Mechanics is presented tog…
Supersymmetric quantum mechanics, the variational method and a new shape invariant potential
Elso Drigo filho, Regina Maria Ricotta
The association of the variational method with supersymmetric quantum mechanics through an ansatz for the superpotential is reviewed and the approximate energy spectra of non-exact…
Remark on Shape Invariant Potential
Elso Drigo Filho, Regina Maria Ricotta
The usual concept of shape invariance is discussed and one extension of this concept is suggested.
