Global solution of the cubic oscillator
E. M. Ferreira, J. Sesma
The eigenstates of a real or complex cubic anharmonic oscillator are investigated using original and alternative methods. The procedure consists of determining global solutions of…
One-dimensional quantum scattering by a parabolic odd potential
Erasmo M. Ferreira, Javier Sesma
Quantum scattering by a one-dimensional odd potential proportional to the square of the distance to the origin is considered. The Schrödinger equation is solved exactly and explici…
The generalized quantum isotonic oscillator
Javier Sesma
Recently, it has been proved that a nonlinear quantum oscillator, generalization of the isotonic one, is exactly solvable for certain values of its parameters. Here we show that th…
A new strategy to find bound states in anharmonic oscillators
Francisco J. Gomez, Javier Sesma
A very simple procedure to calculate eigenenergies of quantum anharmonic oscillators is presented. The method, exact but for numerical computations, consists merely in requiring th…
