摘要

The entanglement characteristics including the so-called sudden death effect between two identical two-levelatoms trapped in two separate cavities connected by an optical fiber are studied.The results show that the timeevolution of entanglement is sensitive not only to the degree of entanglement of the initial state but also to the ratiobetween cavity-fiber coupling (v) and atom-cavity coupling (g).This means that the entanglement dynamics can becontrolled by choosing specific v and g.
