Dynamics of atom-field correlations and single-mode nonclassicalities presentin the resonant Jaynes-Cummings model are investigated using negativity andentanglement potential for a set of initial states. The study has revealed theinterplay between three different types of nonclassicality present in the modeland established that the nonclassicality is continuously exchanged between thefield and atom through the atom-field correlations. Further, it is observedthat the entanglement potential does not capture all the single-modenonclassicality and there exists some residual nonclassicality in the reducedsingle-mode states at the output of the beam splitter which is not captured bythe entanglement in which single-mode nonclassicality is quantitatively mappedin Asboth's criterion. Additional layers of beam splitters are added to depleteall the nonclassicality and to reveal that almost all the residualnonclassicality is captured with three layers of beam splitters. Further, thereduced states of the atom and field have zero (non-zero) quantum coherence inthe Fock basis when the atom-field correlations are maximum if the field (oratom) has zero (non-zero) quantum coherence initially.
