Abstract
- We theoretically introduce two new photon-modulated atomic coherent states (ACSs) via using the Schwinger bosonic representation of the angular momentum operators (the sequential operations J ± n ) on an ACS, and investigate their nonclassicality using the Wigner distribution, photon number distribution, and entanglement entropy. It is found that photon-modulated ACSs possess more stronger nonclassicality than the original ACS in certain regions of τ, the nonclassicality enhances with increasing number n of the operations J ± and the operation J + ( − ) n enhances the entanglement in the region of small (large) τ.
