Stability of the minimum solitary wave of a nonlinear spinorial model
(Physical Review D, 1986) Álvarez Alonso, Amador; Soler, M.
It is shown that the minimum solitary wave of a nonlinear spinorial model is unstable under charge-preserving deformations via a radiative decay. We analyze the cause of this decay.
Spinorial solitary wave dynamics of a (1+3)-dimensional model
(Physical Review D, 1985) Álvarez Alonso, Amador
The interaction dynamics for the minimum solitary waves of the classical Dirac field with scalar selfinteraction in 1+3 dimensions is exhibited. It is shown that the possibility to use these waves as models of elementary particles, as has been suggested before, is ruled out by the radiative nature of the above interaction.
Evolución temporal de un campo clásico de dirac unidimensional con autoacoplo escalar

Energetic Stability Criterion for a Nonlinear Spinorial Model
(Physical review letters, 1983) Álvarez Alonso, Amador; Soler, M.
The time evolution of expanded and contracted solitary waves of the Dirac field with scalar self-interaction is exhibited. It is shown that the positivity of the second variation of the energy functional is not a necessary condition for the stability of these waves as has been recently suggested.
Blow-up in nonlinear models of extended particles with confined constituents
(Physical Review D, 1988) Fernández-Rañada, Antonio; Álvarez Alonso, Amador
It is shown that the indefinite character of the charge in classical models of extended particles with confined constituents is a serious handicap since infinite amounts of positive and negative charge can be emitted in some solutions, causing a blow-up in finite time.
