Quasi-exactly solvable hyperbolic potential and its anti-isospectral counterpart
E. Condori-Pozo, M. A. Reyes, H. C. Rosu
We solve the eigenvalue spectra for two quasi exactly solvable (QES) Schrödinger problems defined by the potentials $V(x;γ,η) = 4γ^{2}\cosh^{4}(x) + V_{1}(γ,η) \cosh^{2}(x) + η\lef…
Supersymmetric features of the Error and Dawson's functions
Marco A. Reyes, Rafael Arcos-Olalla
Following a letter by Bassett, we show first that it is possible to find an analytical approximation to the error function in terms of a finite series of hyperbolic tangents from t…
A note on the FKPP equation approached with the hyperbolic scaling
M. A. Reyes, H. C. Rosu
We consider the hyperbolic scaling of the FKPP equation and introduce two solutions of the action functional type in the limit of zero hyperbolic parameter. Furthermore, we show th…
Factorization procedure and new generalized Hermite functions
Marco A. Reyes, M. Ranferi Gutierrez
We propose an alternative factorization for the simple harmonic oscillator hamiltonian which includes Mielnik's isospectral factorization as a particular case. This factorization i…
Three-step master equation: class of parametric stationary solutions
H. C. Rosu, M. A. Reyes, F. Valencia
We examine the three-step master equation from the standpoint of the general solution of the associated discrete Riccati equation. We report by this means stationary master solutio…
Factorization approach for barotropic FRW model with a cosmological constant
J. Socorro, M. A. Reyes, F. A. Gelbert
We apply the technique of standard supersymmetric factorization for any q factor ordering in the Wheeler-DeWitt (WDW) equation for barotropic Friedmann-Robertson-Walker (FRW) minis…
