Abstract
Typically, physicists treat cold atoms in a cavity as simple two-level atoms. Here, the authors go beyond this approximation to show that adding more levels causes light-matter coupling to be time dependent and results in nonlinear behavior. They experimentally confirm these effects using laser-cooled rubidium.
