Description

The final event of the PRIN (Italian Research Project of National Interest) "String Theory as a Bridge between Gauge Theory and Quantum Gravity" will be a three-day conference that will take place at Sapienza University of Rome from 17 to 19 February 2025.

 

Città Universitaria La Sapienza | Turismo Roma La Sapienza University of Rome - Pava Education

 

                  

This project is a collaboration between theoretical physics groups at INFN, SISSA, University of Roma Tor Vergata, Turin University, University of Piemonte Orientale, and Sapienza University of Rome.

The topics of the workshop will range from gravitational wave phenomenology to modern approaches to scattering amplitudes, from quantum field theories in the presence of defects to the construction of novel theories with (broken) superconformal symmetry, from cosmological perturbations to highly excited strings and black-hole microstates.

      Quantum Cross-section of Near-extremal Black Holes

      We explore how to detect the large quantum fluctuations in the throat of a near-extremal black hole, where the dynamics are governed by the Schwarzian theory. To this end, we scatter a low-frequency wave of a massless, minimal scalar off the black hole and calculate the absorption cross-section. We find that in the strongly coupled regime the absorption cross-section exceeds the semiclassical prediction. We conclude that a measurement showing an enhanced absorption cross-section serves as a clear signature of the large quantum fluctuations in the geometry.

      Non-BPS branes as holographic symmetry operators

      We propose a holographic description of the operators implementing continuous global symmetries that are dual to superstring gauge fields in terms of non-BPS D- branes, and consider some possible further extensions.

      Integrated correlators in a N=2 SYM theory with fundamental flavors

      I will discuss recent developments in the study of integrated 4-point correlators of primary operators in a four-dimensional \mathcal{N}=2 superconformal field theory with SU(N) gauge group and matter in the fundamental and anti-symmetric representations. Exploiting supersymmetric localization, it is possible to map the computation of these correlators to an interacting matrix model and obtain expressions that are valid for any value of the ’t Hooft coupling in the large-N limit of the theory. In particular, I will focus on the strong-coupling regime, showing how to extract analytically the strong-coupling expansion of the integrated correlators from these exact expressions.

      Source Multipoles and Energy-Momentum Tensors for Spinning Black Holes and Other Compact Objects

      Inspired by the scattering amplitude program applied to General Relativity, we define the most general energy-momentum tensor constructed from mass and spin in momentum space and arbitrary dimensions. Through this approach, we establish a one-to-one correspondence between the form factors that characterize the source and the gravitational multipole moments of the induced spacetime, providing a precise definition of source multipoles in a relativistic context and identifying a new class of multipoles, which we call “stress multipoles”. We then apply this formalism to determine the source of rotating black holes and subsequently use it to construct horizonless Kerr mimickers.

      A compendium of logarithmic corrections in AdS/CFT

      I will discuss logarithmic corrections to various CFT partition functions in the context of the AdS_4/CFT_3 correspondence for theories arising on the worldvolume of M2-branes. I will use four-dimensional gauged supergravity and heat kernel methods to derive general expressions for the logarithmic corrections to the gravitational on-shell action or black hole entropy for a number of different supergravity backgrounds. I will outline several subtleties and puzzles in these calculations and will show how they provide non-trivial precision tests of the AdS/CFT correspondence. These results have important implications for the existence of scale separated AdS vacua in string theory and for effective field theory in AdS more generally.
