Stringy gravity, interacting tensionless strings and massless higher spins

TL;DR

This paper explores the implications of a strong AdS/CFT correspondence for highly stringy regimes, revealing insights into tensionless strings, higher spin fields, and phase transitions in AdS_5 backgrounds.

Contribution

It provides new results connecting supersymmetric Yang-Mills theory to tensionless strings and higher spins, and analyzes thermodynamics indicating a Hawking-Page transition in extreme string limits.

Findings

Properties of tensionless strings and higher spin fields are derived from N=4 SYM.

Evidence of a Hawking-Page phase transition at high temperatures.

Thermodynamic analysis suggests a phase change in the extreme string regime.

Abstract

Consequences of a strong version of the AdS/CFT correspondence for extremely stringy physics are examined. In particular, properties of N = 4 supersymmetric Yang-Mills theory are used to extract results about interacting tensionless strings and massless higher spin fields in an AdS_5 x S^5 background. Furthermore, the thermodynamics of this model signals the presence of a Hawking-Page phase transition between AdS_5 space and a "black hole"-like high temperature configuration even in the extreme string limit.
