Tensionless Strings Limits in 4D Conformal Manifolds

Explore a 31-minute conference talk by Jose Calderon-Infante on tensionless string limits in 4D conformal manifolds, presented at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) during the Thematic Programme on "The Landscape vs. the Swampland" in July-August 2024. Delve into the three distinct infinite distance limits in the conformal manifolds of four-dimensional superconformal field theories with large N limits. Examine how these limits correspond to different strings becoming tensionless in AdS, as supported by the CFT Distance Conjecture parameter and large N Hagedorn temperature. Discover the first Distance Conjecture convex hull for a CFT and its connection to no separation of scales in AdS. Gain insights into the physical distinctions between these limits based on the density of states at high energies and their implications for higher-spin fields in AdS/CFT correspondence.
