WebAbstract: In 1954, Dicke predicted that a system of quantum emitters confined to a subwavelength volume would produce a superradiant burst. For such a burst to occur, the emitters must be in the special Dicke state with zero dipole moment. We show that a superradiant burst may also arise for non-Dicke initial states with a nonzero dipole … WebThis function can be used to build arbitrary states in the Dicke basis:math:`\lvert j, m\rangle\langle j, m'\rvert`. We create coefficients for each (j, m, m1) value in the dictionary jmm1. The mapping for the (i, k) index of the density matrix to the :math:`\lvert j, m\rangle` values is given by the cythonized function `jmm1_dictionary`.
