Abstract The pure state dynamical evolution of the atomic as well as the field states in the two-photon Jaynes Cumming model with a Kerr-like medium for the field initially in the coherent state is investigated under the high-field approximation ($\bar{n}$＞＞1). Analytic expressions of the disentanglement conditions and the relevant disentangled states are derived, which are closely related to Kerr nonlinear coupling constant. This study also reveals that the initial atomic excited state can be evolved into the atomic dipole squeezed state.

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.
