The creation of a topological vortex by a superradiant scattering of a Laguerre-Gaussian (LG) beam off an atomic Bose-Einstein condensate (BEC) is theoretically investigated. It is shown that scattered superradiant radiation ...

We adopt the coherence and builtin swap mechanism in sequential superradiance as a tool for obtaining continuousvariable (electric/magnetic fields) quantum entanglement of two counterpropagating pulses emitted from the two ...
