Multipartite Atom(s)-Field Entanglement in Cavity QED


We consider the entanglement between a multi-level atom and two cavity modes for a cavity QED system, find that cross-correlations between the two modes are witness to atom-field entanglement. Concurrences and log negativities are also calculated.
