本文提出了一种系统地研究相对论场论的非相对论极限的形式。通过引入一个简单的、非局部的场重定义，我们可以将一个给定的用实值、自相互作用标量场表示的相对论理论转化为一个描述复标量场的等价理论。我们的低能量有效理论结合了来自非消失动量的修正，以及来自快速振荡项对主导的、缓慢变化的场分量的反作用的修正。我们的新方法的可能应用包括轴子暗物质，尽管这里开发的方法也应该适用于其他场论的低能量极限。
In this paper we develop a formalism for studying the nonrelativistic limit of relativistic field theories in a systematic way. By introducing a simple, nonlocal field redefinition, we may transform the description of a given relativistic theory in terms of a real-valued, self-interacting scalar field into an equivalent theory, describing a complex scalar field. Our low-energy effective theory incorporates corrections from nonvanishing momentum as well as from the backreaction of fast-oscillating terms on the behavior of the dominant, slowly varying component of the field. Possible applications of our new approach include axion dark matter, though the methods developed here should be applicable to the low-energy limits of other field theories as well.
