Dynamical generation of maximally entangled states in two identical cavities

The generation of entanglement between two identical coupled cavities, each containing a single three-level atom, is studied when the cavities exchange two coherent photons and are in the N = 2,4 manifolds, where N represents the maximum number of photons possible in either cavity. The atom-photon state of each cavity is described by a qutrit for N = 2 and a five-dimensional qudit for N = 4. However, the conservation of the total value of N for the interacting two-cavity system limits the total number of states to only 4 states for N = 2 and 8 states for N = 4, rather than the usual 9 for two qutrits and 25 for two five-dimensional qudits. In the N = 2 manifold, two-qutrit states dynamically generate four maximally entangled Bell states from initially unentangled states. In the N = 4 manifold, two-qudit states dynamically generate maximally entangled states involving three or four states. The generation of these maximally entangled states occurs rather rapidly for large hopping strengths. The cavities function as a storage of periodically generated maximally entangled states.
