Nordita, Stockholm (Sweden)

This Nordita program is devoted to amplitudes- and QFT-inspired analytic methods for gravity at all scales. The topics covered will include: recent progress for gravitational amplitudes, new perturbative/effective formalisms, and relations between gravity and gauge theory. Higher-order calculations for: post-Newtonian/Minkowskian and self-force corrections to the gravitational potential/wave emission, cosmological correlators and ultraviolet physics probing quantum gravity, and applications to string theory. Challenges of incorporating spin and tidal effects in general relativity, and scattering amplitudes for Kerr black holes. Flat space holography in the form of celestial amplitudes, asymptotic symmetries and gravitational memory.

QFT techniques are routinely applied to systems with boundaries and defects, often with remarkable success. However, in systems with strong interactions many of the important questions remain intractable. Luckily, the rapid development of novel approaches to strongly-interacting QFTs opens a new avenue to study boundaries, defects and impurities. Prominent examples include the Anti-de-Sitter/Conformal Field Theory correspondence and holographic duality, integrability, the conformal bootstrap, non-perturbative supersymmetry methods, the use of entanglement entropy and other quantum information measures, anomalies and higher-form symmetries, hydrodynamics of QFTs, and more.
