论文摘要
我们为相互作用的波系统中的预脂化提出了一个更一般的设置。这个想法在于将多波动相互作用分为琐碎和非琐碎的相互作用。琐碎的相互作用将打扮波,并导致一个不太强烈的相互作用系统,在统计学上等同于原始系统。考虑到这一点,我们发现prethermalization不仅发生在弱相互作用的体制中,而且还发生在强烈的相互作用方案中。不可逆转的均衡过程受Zakharov方程的控制,从中,预计热缩放时间的双缩放时间。最后,该理论在数值实验中得到了很好的证实。
We propose a more general setup for prethermalization in the system of interacting waves. The idea lies in dividing the multi-wave interactions into trivial and nontrivial ones. The trivial interactions will dress waves and lead to a less strongly interacting system which is statistically equivalent to the original one. With this in mind, we find that prethermalization occurs not only in the weakly interacting regime but also in the strongly interacting regime. The irreversible process towards equilibrium is governed by the Zakharov equation, from which double scaling of the thermalization time is expected. Finally, the theory is well confirmed in numerical experiments.
