三维中高自旋场与平面薛定谔方程的非相对论极限

Non-relativistic limit for Higher Spin Fields and Planar Schroedinger Equation in 3D

Abhijeet Dutta

AI总结:

本文研究三维闵可夫斯基时空中高自旋场的非相对论极限,在运动方程和作用量两个层面建立可推广至任意高自旋场的系统化程序,并给出薛定谔方程作为该极限下的动力学方程。

摘要:

高自旋(HS)场自然出现在弦论中,它们被视为暗物质的一种候选,也可能作为凝聚态系统中的集体激发出现。在某些情况下,人们可以在非相对论框架下研究高自旋场。因此,了解高自旋场的非相对论极限以及如何在该极限下将薛定谔方程作为动力学方程求出,是很有意义的。在本文中,我们考虑三维闵可夫斯基时空中高自旋场的非相对论极限。我们同时在运动方程层面和作用量/拉格朗日密度层面进行研究。我们在两种框架下都找到了系统化的程序,并证明这些程序可以推广到任意高自旋场。

英文摘要:

Higher spin (HS) fields naturally occur in string theory, they are considered as a candidate for dark matter and may also appear as a collective excitation in condensed matter systems. In some cases one may study the HS fields in the non-relativistic settings. Thus, it is of interest to know the non-relativistic limit of HS fields and how to find the Schroedinger equation as the dynamical equation in this limit. In this paper, we consider the non-relativistic limit of HS fields in Minkowskian spacetime in 3D. We work both at the level of equation of motion and action/Lagrangian density. We find the systematic procedures in both settings and show that they can be generalized to arbitrary HS fields.
