Temporal dynamics in the Bragg reflection of light by cold atoms: Flash effect and superradiant decay
The authors study the transient optical response of a Bragg mirror made of cold atoms trapped in a one-dimensional lattice. They find that after the switch-off of the incoming beam, depending on its frequency, the reflected intensity can temporarily increase, or, on the contrary, can undergo a decay much faster than the natural timescale of the response of individual atoms.
