    "abstract": "Intracavity and external third order correlations in the damped nondegenerate\nparametric oscillator are calculated for quantum mechanics and stochastic\nelectrodynamics (SED), a semiclassical theory. The two theories yield greatly\ndifferent results, with the correlations of quantum mechanics being cubic in\nthe system\u0027s nonlinear coupling constant and those of SED being linear in the\nsame constant. In particular, differences between the two theories are present\nin at least a mesoscopic regime. They also exist when realistic damping is\nincluded. Such differences illustrate distinctions between quantum mechanics\nand a hidden variable theory for continuous variables.",
