Kinetics of superradiance for a system of two-level emitters interacting with the quantum electromagnetic field is studied. A closed set of equations for atomic correlation functions is obtained which takes into account new decoupling of three- particle correlators. These equations yield a better description of experimentally observed shape of superradiant peak than the standard theories.

Superradiance in spin- j particles: Effects of multiple levels

Guin-Dar Lin, Susanne F. Yelin

We study the superradiance dynamics in a dense system of atoms each of which can be generally a spin- $j$ particle, with $j$ an arbitrary half-integer. We generalize Dicke's superradiance point of view to multiple-level systems and compare the results based on a novel approach we developed previously [Lin and Yelin, Adv. Atom. Mol. Opt. Phys. 61, in press (2012)]. Using this formalism we derive an effective two-body description that shows cooperative and collective effects for spin- $j$ particles, taking into account the coherence of transitions between different atomic levels. We find that superradiance, which is well known as a many-body phenomenon, can also be modified by multiple-level effects. We also discuss the feasibility and propose that our approach can be applied to polar molecules, for their vibrational states have a multilevel structure which is partially harmonic.We study the superradiance dynamics in a dense system of atoms each of which can be generally a spin-$j$ particle, with $j$ an arbitrary half-integer.
