光子辐射振幅的计算

Computation of the radiation amplitude of oscillons

Gyula Fodor, Péter Forgács, Zalán Horváth, Márk Mezei

摘要:

本文采用匹配渐近级数展开和Borel求和的小振幅展开方法,解析地计算了一维标量场理论中小振幅介子(长寿命、空间局域、时间相关解)的辐射损失。辐射的振幅超出了微扰理论中的所有阶数,并且所使用的方法已经由Segur和Kruskal在Phys.Rev.Lett中发展。58,747(1987)中所述。我们的结果与长时间数值模拟的结果符合得很好。

英文摘要:

The radiation loss of small amplitude oscillons (very long-living, spatially localized, time dependent solutions) in one dimensional scalar field theories is computed in the small-amplitude expansion analytically using matched asymptotic series expansions and Borel summation. The amplitude of the radiation is beyond all orders in perturbation theory and the method used has been developed by Segur and Kruskal in Phys. Rev. Lett. 58, 747 (1987). Our results are in good agreement with those of long time numerical simulations of oscillons.
