| contents | We apply the Wigner-Yanase skew information, as a quantum information quantifier of atomic non-classicality in the dynamics generated by the anti-Jaynes-Cummings (AJC) Hamiltonian when a two-level atom in an initial atomic ground state, couples to a single mode of squeezed coherent light. We investigate the effect of variation of squeeze parameter, field intensity, and coupling strength parameter, on the dynamics of the Wigner-Yanase skew information. We observe that time-evolution of the Wigner-Yanase skew information records mixed state values for all variations of squeeze parameter, field intensity and coupling strength parameter, congruent with squeezing effects. |
