标量场理论中的共振振荡:(某些)振荡能永远存在吗?

Resonant Configurations in Scalar Field Theories: Can (Some) Oscillons Live Forever?

Marcelo Gleiser, Max Krackow

摘要:

我们调查的长寿的drons数值,特别注意径向对称drons已被证明有一个无限长的寿命。在两个空间维度中,还没有看到光子衰变。在三维空间中,特定的初始高斯配置似乎会导致寿命峰值的光子,这些光子的寿命已经被证明是无限的。我们研究这样的“共振”在两个和三个空间维度,应用两个测试来研究它们的寿命:参数共振和维里化。没有提供一个正式的证明,我们的数值结果,在其精度范围内,提供支持的猜想,在这两个维度,共振的光子可能是无限长寿。

英文摘要:

We investigate the longevity of oscillons numerically, paying particular attention to radially-symmetric oscillons that have been conjectured to have an infinitely-long lifetime. In two spatial dimensions, oscillons have not been seen to decay. In three spatial dimensions, specific initial Gaussian configurations seem to lead to oscillons with spikes in lifetime that have been conjectured to be infinite. We study such ``resonant'' oscillons in two and three spatial dimensions, applying two tests to study their longevity: parametric resonance and virialization. Without offering a formal proof, our numerical results, within their precision, offer support for the conjecture that, in both dimensions, resonant oscillons may be infinitely long-lived.
