Experimental observation of violent relaxation

M. C. Braidotti, M. Lovisetto, et al.

A groundbreaking optical experiment has directly observed the phenomenon of violent relaxation, a process crucial to understanding the formation of structures in the universe. Conducted by a team of researchers including Maria Chiara Braidotti and her colleagues, this study offers a fresh perspective on how galaxy formation can be mirrored through controlled optical dynamics.

Abstract

Structures in the Universe, from globular clusters to galaxies, aren't described by standard equilibrium statistical mechanics. Instead, they form through "violent relaxation," a process theoretically proposed and numerically modeled but never directly observed. This paper details a table-top optical experiment directly observing violent relaxation. The optical dynamics analogously represent 2D galaxy formation, controllable parameters emulating gravitational quantum and classical dark matter models.
