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…
Pullback of the Volume Form, Integrable Models in Higher Dimensions and Exotic Textures
C. Adam, P. Klimas, J. Sanchez-Guillen +1
A procedure allowing for the construction of Lorentz invariant integrable models living in d+1 dimensional space-time and with an n dimensional target space is provided. Here, inte…
Perturbations of the signum-Gordon model
Pawel Klimas
We investigate a perturbation of a scalar field model (called here the signum-Gordon model) with the potential . The perturbation generalizes the signum-Gordon model to t…
