从有效场论看Dirac理论的非相对论极限

Nonrelativistic Limit of Dirac Theory From Effective Field Theory

Rodrigo Corso B. Santos, Pedro R. S. Gomes

摘要:

本文在有效场论的框架下分析了狄拉克理论的低能非相对论极限。通过积分出狄拉克场的高能模,给出了两个分量的Weyl旋量的组合,我们得到了剩余分量的低能有效作用量,其运动方程可以在要求波函数归一化后与泡利-薛定谔方程进行比较。然后,我们讨论的各向异性尺寸分析,这是适合于非相对论理论的背景下,在有效的行动中的条款的相关性。

英文摘要:

In this work we analyze the low energy nonrelativistic limit of Dirac theory in the framework of effective field theory. By integrating out the high energy modes of Dirac field, given in terms of a combination of the two-components Weyl spinors, we obtain a low energy effective action for the remaining components, whose equation of motion can then be compared to the Pauli-Schrödinger equation after demanding normalization of the wave function. We then discuss the relevance of the terms in the effective action in the context of an anisotropic dimensional analysis which is suitable for nonrelativistic theories.
