Scattering length for Lennard-Jones potentials
F. J. Gomez, J. Sesma
We present an exact procedure that allows one to calculate the scattering lenth for any potential expressed as an algebraic sum of inverse powers of the interatomic distance. We ap…
Spiked oscillators: exact solution
F. J. Gomez, J. Sesma
A procedure to obtain the eigenenergies and eigenfunctions of a quantum spiked oscillator is presented. The originality of the method lies in an adequate use of asymptotic expansio…
The Role of Resonances in the Stochastic Limit
F. Gomez
In the stochastic limit the resonances play a fundamental role because they determine the generalized susceptivities which are the building blocks of all the physical information w…
Quantum anharmonic oscillators: a new approach
F. J. Gomez, J. Sesma
The determination of the eigenenergies of a quantum anharmonic oscillator consists merely in finding the zeros of a function of the energy, namely the Wronskian of two solutions of…
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…
