Workshop on "Selected topics on quantum gravity"

The workshop will take place at ULB - Campus Plaine in Brussels
21 - 22 February 2022. Physical presence is favoured but given the sanitary situation, the workshop will adopt a hybrid format with online and physical participation.


This Solvay workshop is the first of a series of meetings devoted to new developments in quantum gravity. Topics to be addressed in this first session include: information in quantum gravity, wormholes, dynamics of entanglement in QFT and AdS/CFT, complexity in QFT and holography, quantum chaos, soft hair, asymptotic symmetries, symmetries at the horizon, insights from the Wheeler-De Witt equation, quantum de Sitter space, bounds on quantum gravity and holography from amplitudes.
