电磁场理论的对偶对称Action

Duality-symmetric Action for Electromagnetic Theory with Electric and Magnetic Sources

Choonkyu Lee, Hyunsoo Min

摘要:

对于SL(2,\textbf{R})对偶不变的Maxwell电动力学的推广,我们通过引入一对四势$A^μ$和$B^μ$,以一种明智的方式,形成了一个局部的、明显对偶对称的Zwanziger型作用量. SL(2,\textbf{R})对偶变换在两个势$A^μ$和$B^μ$上以简单的线性方式起作用。在包含带电源场的量子理论中,这个作用量可以被改写为SL(2,\textbf{Z})不变作用量。还给出了SL(2,\textbf{R})对偶不变Born-Infeld电动力学的Zwanziger型作用量,它对弦论中的D膜动力学有重要意义.

英文摘要:

For the SL(2,\textbf{R}) duality-invariant generalization of Maxwell electrodynamics in the presence of both electric and magnetic sources, we formulate a local, manifestly duality-symmetric, Zwanziger-type action by introducing a pair of four-potentials $A^μ$ and $B^μ$ in a judicious way. On the two potentials $A^μ$ and $B^μ$ the SL(2,\textbf{R}) duality transformation acts in a simple linear manner. In quantum theory including charged source fields, this action can be recast as a SL(2,\textbf{Z})-invariant action. Also given is a Zwanziger-type action for SL(2,\textbf{R}) duality-invariant Born-Infeld electrodynamics which can be important for D-brane dynamics in string theory.
