Nonclassicality generated by propagation of atoms through a cavity field

► V-type three-level atoms and a single-mode cavity field. ► Quasiprobability Q function, Wigner distribution, Mandelʼs Q parameter and squeezing. ► Inducing nonclassicality into the character of a pure classical coherent state. ► Thermal field shows sub-Poissonian as well as squeezing property after interaction.
