摘要

考虑一个经典的（1+1）维小振幅λ振荡。对于所有阶的λ，振荡解都是周期性的。我们研究这种周期构型的小扰动。这些扰动本身是周期的，直到一个单矩阵。我们显式地找到了单矩阵的特征向量，它是振子的正模的类似物。Dashen， Hasslacher和Neveu使用这样的特征向量来量化正弦戈登呼吸子，我们怀疑它们将是量化振荡所必需的。无论选择何种模型，我们的结果都表明，低振幅振荡不反映小振幅辐射。

Normal modes of the small-amplitude oscillon

Consider a classical (1+1)-dimensional oscillon of small amplitude ϵ. To all orders in ϵ, the oscillon solution is exactly periodic. We study small perturbations of such periodic configurations. These perturbations are themselves periodic up to a monodromy matrix. We explicitly find the eigenvectors of the monodromy matrix, which are the analogues of normal modes for oscillons. Dashen, Hasslacher and Neveu used such eigenvectors to quantize the sine-Gordon breather, and we suspect that they will be necessary to quantize the oscillon. Our results, regardless of the chosen model, suggest that low amplitude oscillons do not reflect small amplitude radiation.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
