    "abstract": "For an atom in an externally driven cavity, we show that special initial\nstates lead to near-disentangled atom-field evolution, and superpositions of\nthese can lead to near maximally-entangled states. Somewhat counterintutively,\nwe find that (moderate) spontaneous emission in this system actually leads to a\ntransient increase in entanglement beyond the steady-state value. We also show\nthat a particular field correlation function could be used, in an experimental\nsetting, to track the time evolution of this entanglement.",
