Dispersion relation of the non-linear Klein-Gordon equation through a variational method
P. Amore, A. Raya
We derive approximate expressions for the dispersion relation of the nonlinear Klein-Gordon equation in the case of strong nonlinearities using a method based on the Linear Delta E…

Gauge Invariance and Construction of the Fermion-Boson Vertex in QED3
A. Raya
We study the specific role that the Ward-Green-Takahashi identity plays in the restoration of the gauge independence of the physical observables related to the phenomenon of Dynami…
