"Infrared Physics: Asymptotic & BMS symmetry, soft theorems, memory, information paradox and all that"

Brussels, 16 - 18 May 2018 (ULB - Campus Plaine - Solvay Room)

Seemingly unrelated topics, such as the asymptotic structure of spacetime, infrared properties of massless particles in quantum field theory, or measurable effects related to gravitational waves, have been developed to some extent independently since the 1960s. Recent progress indicates that these subjects do admit an interesting intersection.


The purpose of the present workshop is to give a snapshot of the advances in different communities (general relativity, both mathematical and observational, quantum field theory, string theory), with the hope to increase interactions transcending traditional subdivisions.

NB: Two other workshops on closely related topics are organized by the Solvay Institutes before and after, please see the links below:

"Cosmological Frontiers in Fundamental Physics".
