Quantum trajectory theory of superradiant emission from randomly distributed atomic samples
Ryan Nowak, James Clemens · Journal of the Optical Society of America B · 2008
We consider the directed superradiant emission from a collection of N two-state atoms with arbitrary spatial locations within the framework of quantum trajectory theory and without a single-mode assumption. The formalism is developed around an unravelling of the master equation in terms of source mode quantum jumps. A modified boson approximation is made to treat the many-atom case, where it is found that strong directional superradiance occurs for a few thousand atoms, even with randomized atomic positions.
