Variational Formalism for the Klein-Gordon Oscillon / I.V.Barashenkov, N.V.Alexeeva // Physical Review D [Electronic resource]. – 2023. – Vol.108, No.9. – P.096022. – URL: https://doi.org/10.1103/PhysRevD.108.096022. – Bibliogr.:67.

The variational method employing the amplitude and width as collective coordinates of the Klein-Gordon oscillon leads to a dynamical system with unstable periodic orbits that blow up when perturbed. We propose a multiscale variational approach free from the blowup singularities. An essential feature of the proposed trial function is the inclusion of the third collective variable: a correction for the nonuniform phase growth. In addition to determining the parameters of the oscillon, our approach detects the onset of its instability.
