Title: Amplitude modulations and resonant decay of excited oscillons
(Submitted on 1 Mar 2024 (v1), last revised 13 Mar 2024 (this version, v2))
Abstract: We show that the decay of strongly excited oscillons in a single vacuum model reveals a chaotic, fractal-like pattern very much like one found in kink-antikink collision 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 quasi-breathers inside the constituent oscillon.
