Abstract A scheme to generate the two-mode field entangled states is proposed, based on the Raman interaction of an effective two-level atom with the pump and Stokes fields. The degree of the entanglement between the two field modes in the entangled states is also studied.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
