A workshop on “Carrollian physics” will take place at the University of Mons from the 12th to the 16th of September.

Carrollian physics? What is it?

Non-relativistic, or Galilean, physics can be obtained from Einstein’s theory of special relativity in the limit in which the speed of light tends to infinity. Carrollian space-times are obtained in the alternative limit in which the speed of light tends to zero. This limit, whose properties were studied for the first time by J.-M. Levy-Leblond in 1965, is quite disorienting from a physical point of view.

In fact, the physical laws thus obtained are so surprising (one could say so crazy) that J.-M. Levy-Leblond suggested naming them after Lewis Carroll: he pointed out that, like this new physics, Alice in Wonderland‘s adventures often seem to make fun of temporal causality.

The Carrollian limit may seem, at first sight, very difficult to justify physically. At a closer look, however, one realises that this limit arises in multiple contexts within the framework of general relativity: when we approach the singularity of the Big-Bang; when the cosmological constant in the AdS/CFT correspondence tends to zero; when one studies the physical processes taking place at the horizon of a black hole. These are all examples, among many others, of Carrollian limits.

It is therefore unsurprising that Carrollian physics has recently played a key role in several directions of research, including holographic and fluid/gravity correspondences, the study of asymptotically flat spacetimes at their null boundaries and the BMS symmetries associated with them, the study of the geometry of light-like hypersurfaces such as the horizons of black holes or the cosmological apparent horizons.

The main purpose of the CARROLL WORKSHOP is to gather people who are currently participating to this research endeavor. Anyone engaged in the fascinating Carrollian research effort is most welcome to join us to take this opportunity to share innovative ideas and perhaps create new collaborative motions.
