    "abstract": "The Jaynes-Cummings model is the simplest fully quantum model that describes\nthe interaction between light and matter. We extend a previous analysis by\nPhoenix and Knight (S. J. D. Phoenix, P. L. Knight, Annals of Physics 186,\n381). of the JCM by considering mixed states of both the light and matter. We\npresent examples of qualitatively different entropic correlations. In\nparticular, we explore the regime of entropy exchange between light and matter,\ni.e. where the rate of change of the two are anti-correlated. This behavior\ncontrasts with the case of pure light-matter states in which the rate of change\nof the two entropies are positively correlated and in fact identical. We give\nan analytical derivation of the anti-correlation phenomenon and discuss the\nregime of its validity. Finally, we show a strong correlation between the\nregion of the Bloch sphere characterized by entropy exchange and that\ncharacterized by minimal entanglement as measured by the negative eigenvalues\nof the partially transposed density matrix.",
