Variational supersymmetric approach to evaluate Fokker–Planck probability
Autor: Elso Drigo Filho, Gláucia Rosângela Peglow Borges, R. M. Ricotta
Publikováno v: Physica A: Statistical Mechanics and its Applications. 389:3892-3899
In this work we introduce a method to determine the time dependent probability density for the one-dimensional Fokker–Planck equation. The treatment is based in an analysis of the Schrodinger equation through the variational method associated to th

Hamiltonian hierarchy of pseudo-potentials
Autor: Rita de Cassia dos Anjos, Elso Drigo Filho, R. M. Ricotta
Publikováno v: Physica Scripta. 76:689-692
The general structure of the Hamiltonian hierarchy of the pseudo-Coulomb and pseudo-Harmonic potentials is constructed by the factorization method within the supersymmetric quantum mechanics (SQMS) formalism. The excited states and spectra of eigenfu

Supersymmetric variational energies of 3d confined potentials
Autor: Elso Drigo Filho, R. M. Ricotta
Publikováno v: Physics Letters A. 320:95-102
Within the approach of Supersymmetric Quantum Mechanics associated with the variational method a recipe to construct the superpotential of three dimensional confined potentials in general is proposed. To illustrate the construction, the energies of t

Quantum confinement in hydrogen bond of DNA and RNA
Autor: C S dos Santos, E. Drigo Filho, R. M. Ricotta
Publikováno v: Journal of Physics: Conference Series. 597:012033
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

General structures of Hamiltonian hierarchies
Autor: R. M. Ricotta, R. C. dos Anjos, Elso Drigo Filho
Publikováno v: Journal of Physics: Conference Series. 128:012041
Three dimensional exactly solvable quantum potentials for which an extra term of form 1/r2 has been added are shown to maintain their functional form which allows the construction of the Hamiltonian hierarchy and the determination of the spectra of e
