标题： Amplitude modulations and resonant decay of excited oscillons

摘要： 我们证明，在单真空模型中，强烈激发的振子的衰减呈现出一种混沌的、类似分形的模式，这与在$\phi^4$模型中孤子-反孤子碰撞中发现的模式非常相似。 这种结构可以归因于由构成振子的振幅调制所触发的共振能量转移机制。 我们还发现证据表明，这些调制是构成振子内部两个准束缚态的运动所产生的。 显示英文摘要

摘要： 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.
