General

The detection of gravitational waves from binary systems composed of black holes and/or neutron stars by the LIGO/Virgo/KAGRA collaborations has initiated a new era for studying the cosmos. Yet again gravity is at the center of fundamental physics, both for experiment and theory, and we are heading towards the high-precision frontier. Analytical approaches constitute the future of gravitational waves, cosmology and quantum gravity. Remarkably, quantum field theory provides the mathematical tool of scattering amplitudes which display remarkable simplicity when applied to the non-linear problem of gravity.

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.

 


Themes and preliminary program schedule
