摘要
We propose a scheme for constructing entangled coherent states among two atoms with the presence of single-mode bosonic field mode, considered as noise mode, through non-localizing the respective Lie algebras of the atoms and field. It is observed that, due to the non-localized nature of the associated raising and lowering operators of the related Lie algebras, the constructed coherent state becomes entangled on the one hand, and on the other hand, it is figured out that the existence of the noise mode causes the degradation of constructed atomic entanglement. Also, our proposed dynamical approach for generating the constructed coherent states is discussed.
