The complex Dirac Delta, Plemelj formula, and integral representations
J. Julve, R. Cepedello, F. J. de Urries
The extension of the Dirac Delta distribution (DD) to the complex field is needed for dealing with the complex-energy solutions of the Schrödinger equation, typically when calculat…

Inner products of resonance solutions in 1-D quantum barriers
J. Julve, F. J. de Urries
The properties of a prescription for the inner products of the resonance (Gamow states), scattering (Dirac kets), and bound states for 1-dimensional quantum barriers are worked out…

Higher-Derivative Boson Field Theories and Constrained Second-Order Theories
F. J. de Urries, J. Julve, Eduardo J. S. Villaseñor
As an alternative to the covariant Ostrogradski method, we show that higher-derivative relativistic Lagrangian field theories can be reduced to second differential-order by writing…
