主　　题：the photon-modulated spin coherent state nonclassicality photocount distribution Wigner distribution function 

摘      要：Two new photon-modulated spin coherent states(SCSs)are introduced by operating the spin ladder operators J±on the ordinary SCS in the Holstein-Primakoff realization and the nonclassicality is exhibited via their photon number distribution,second-order correlation function,photocount distribution and negativity of Wigner *** results show that the photocount distribution is a Bernoulli distribution and the Wigner functions are only associated with two-variable Hermite *** with the ordinary SCS,the photon-modulated SCSs exhibit more stronger nonclassicality in certain regions of the photon modulated number k and spin number j,which means that the nonclassicality can be enhanced by selecting suitable parameters.
