TL;DR
This paper proposes that Bekenstein entropy can be understood as the entropy of an effective string with adjusted tension, supported by AdS/CFT correspondence calculations relating boundary entropy to bulk string properties.
Contribution
It introduces a novel interpretation of Bekenstein entropy as string entropy with rescaled tension, linking boundary and bulk descriptions via AdS/CFT.
Findings
Bekenstein entropy matches the entropy of a string at the AdS black hole horizon.
The redshifted tension and energy of the string reproduce Bekenstein entropy.
Provides a new perspective on black hole entropy through string theory.
Abstract
We argue that Bekenstein entropy can be interpreted as the entropy of an effective string with a rescaled tension. Using the AdS/CFT correspondence we show that the Bekenstein entropy on the boundary CFT is given by the entropy of a string at the stretched horizon of the AdS black hole in the bulk. The gravitationally redshifted tension and energy of the string match those required to reproduce Bekenstein entropy.
