摘要

In this paper, we study the dynamics of a two-dimensional coupled cavity system under one-excitation condition. We show that the dynamics behaviors are strongly affected by the atom-cavity detuning (Delta) and cavity-cavity hopping upsilon. As a typical application, we apply this system to generate a four-atom W state. Notably, the entangled state generation is deterministic. As a basic research, the result will contribute to the understanding of more complex systems.
