High energy string theory and the celestial sphere

Work with Stephan Stieberger. We elaborate on the connection between the high-energy limit of the string worldsheet and flat-space (celestial) holography at tree level, using steepest descent methods. This reveals a dual description which organizes large-energy expansions on the celestial sphere in terms higher-spin modes of the string, and suggests a worldsheet-based construction of celestial CFT. We also analyze subleading corrections and number-theoretic aspects of open and closed string amplitudes, relevant for tensionless strings.

Previous publications

Thermodynamics of N=2 theories, squared

Work with Davide Polvara and Alessandro Sfondrini, concluding a summer project I was able to contribute to after my time in Cambridge in 2023. We use integrability techniques (thermodynamic Bethe Ansatz) to study the spectrum of strings propagating in 3d AdS with a mixed RR/NSNS flux configuration, in a specific relativistic limit where the dispersion relation simplifies. I was generously supported by the Fondation du Domaine de Villette.

BMS symmetries of gravitational scattering

This review article arose from my Part III essay at the University of Cambridge, under the guidance of Prahar Mitra. I pedagogically review the infrared triangle of gravity, and explicitly work out the latter for the case of BMS supertranslations. This was the starting point leading to the celestial holography program, which attempts to provide a holographic description of asymptotically flat spacetimes. My work was published a few years later.
