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 Jn±)on an ACS,and investigate their nonclas-sicality 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 7n+(-)enhances the entanglement in the region of small(large)τ.
