Fourier analysis of compact oscillons
Pawel Klimas, Leandro Roza Livramento, João Saldanha Streibel
We present a new derivation of the exact compact oscillon in the signum-Gordon model using Fourier methods. This approach decomposes the oscillon into an infinite, uniformly conver…
Signum-Gordon spectral mass from nonlinear Fourier mode mixing
João S. Streibel, Pawel Klimas
We investigate the emergence of a spectral mass in the signum-Gordon model, a nonlinear field theory characterized by a non-analytic, V-shaped potential where standard perturbative…
Signum-Gordon shock waves in (2+1) and (3+1) dimensions
Pawel Klimas, João Saldanha Streibel
This study introduces novel, exact solutions to the scalar field Signum-Gordon equation that feature a discontinuity near the light cone. These solutions, applicable in higher spat…
On decay of shock-like waves into compact oscillons
F. M. Hahne, P. Klimas, J. S. Streibel
The signum-Gordon model in 1+1 dimensions possesses the exact shockwave solution with discontinuity of the field at the light cone and infinite gradient energy. The energy of a reg…
Scattering of compact oscillons
F. M. Hahne, P. Klimas, J. S. Streibel +1
We study various aspects of the scattering of generalized compact oscillons in the signum-Gordon model in (1+1) dimensions. Using covariance of the model we construct traveling osc…
Oscillons in a perturbed signum-Gordon model
P. Klimas, J. S. Streibel, A. Wereszczynski +1
We study various properties of a perturbed signum-Gordon model, which has been obtained through the dimensional reduction of the called `first BPS submodel of the Skyrme model'. Th…
