In this paper several non-classical properties are described such as the entanglement of bipartite system in the multimode cavities, described by the Jaynes-Cummings as well as the Tavis-Cummings model. The modes are described quantum mechanically, which helps to bring out the non-classical features emerging from the interaction of atoms with the cavity modes. Effects such as the growth of the magnitude of atomic entanglement with the increase of the cavity photon number, arising out of the intensity dependent atom-cavity coupling lead to interesting dissimilarities from the case of entanglement generated by the standard Jaynes-Cummings interaction. The dynamics of a single Rydberg atom in an n-mode cavity are also described by oscillations at the rate of the interaction strength of the atom-field interaction, Finally, we investigate the entanglement dynamics in the presence of cavity dissipation under single mode Tavis-Cummings interaction. The atom-photon interactions and the generation of entanglement mediated through them are expected to play an important role in possible future practical realizations in the field of quantum communications for various atom-photon interaction models considered under single or multimode cavity.
