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…
General inner products for energy eigenstates
J. Julve, S. Turrini, F. J. de Urríes
The features of the inner products between all the types of real and complex-energy solutions of the Schrödinger equation for 1-dimensional cut-off quantum potentials are worked ou…
A perturbation approach to Translational Gravity
J. Julve, A. Tiemblo
Within a gauge formulation of 3+1 gravity relying on a nonlinear realization of the group of isometries of space-time, a natural expansion of the metric tensor arises and a simple…
Dynamical variables in Gauge-Translational Gravity
J. Julve, A. Tiemblo
Assuming that the natural gauge group of gravity is given by the group of isometries of a given space, for a maximally symmetric space we derive a model in which gravity is essenti…
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…
Tunnelling of plane waves through a square barrier
J. Julve, F. J. de Urries
The time evolution of plane waves in the presence of a 1-dimensional square quantum barrier is considered. Comparison is made between the cases of an infinite and a cut-off (shutte…
