Zero-point excitation of a circularly moving detector in an atomic condensate and phonon laser dynamical instabilities
We study a circularly moving impurity in an atomic condensate for the realization of superradiance phenomena in tabletop experiments. The impurity is coupled to the density fluctuations of the condensate and, in a quantum field theory language, it serves as an analog of a detector for the quantum ph...
