Abstract

V originále

We show that the decay of strongly excited oscillons in a single vacuum model reveals a chaotic, fractallike pattern very much like the one found in kink-antikink collisions in the Phi 4 model. This structure can be attributed to the resonant energy transfer mechanism triggered by the modulations of amplitudes of constituent oscillons which form the excited oscillon. We also find evidence that such modulations arise as a motion of two quasibreathers inside the constituent oscillon.
