Energy radiated from a fluctuating selfdual string

TL;DR

This paper calculates the energy radiated by a fluctuating selfdual string using AdS-CFT and extends classical electrodynamics results to six dimensions, revealing a non-local energy expression.

Contribution

It introduces a novel computation of radiated energy from a selfdual string via AdS-CFT and generalizes the Larmor formula to six-dimensional electrodynamics.

Findings

Radiated energy is expressed as a non-local integral over the string world-sheet.

The computation bridges string theory and classical electrodynamics in higher dimensions.

The results provide insights into energy emission mechanisms in higher-dimensional theories.

Abstract

We compute the energy that is radiated from a fluctuating selfdual string in the large $N$ limit of $A_{N-1}$ theory using the AdS-CFT correspondence. We find that the radiated energy is given by a non-local expression integrated over the string world-sheet. We also make the corresponding computation for a charged string in six-dimensional classical electrodynamics, thereby generalizing the Larmor formula for the radiated energy from an accelerated point particle.
