Calogero model

The Calogero model is a mathematical framework describing a system of particles interacting through a specific inverse-square force, meaning the force depends on the inverse of the distance squared between particles. It’s significant in physics because it provides insights into complex quantum systems, integrable systems (where exact solutions are possible), and connections to topics like fractional statistics and condensed matter phenomena. Essentially, it helps scientists understand how particles behave under long-range interactions, with applications spanning quantum mechanics, mathematical physics, and statistical mechanics.
