This paper solves milburn’s intrinsic noise (IN) model for a 3-level atom of anΞ-type interacting with
a coherent cavity field via multiphoton transitions. Therefore, the effects of the intrinsic noise and the
multi-photon interactions are investigated for some quantum phenomena, such as total correlation,
entanglement, and atomic inversion. In general, we found that the collapse-revival phenomenon
occurs during the oscillatory behaviour of atomic population dynamics. In addition, the birth-death
phenomenon is observed in the negativity dynamics. Entropy, negativity, and mutual information
have various dynamics. It is found that, as the entropy increases, the negativity and mutual
information diminish to stationary levels. When intrinsic noise is considered, all the phenomena of
atomic inversion, entropies, negativity and mutual information exhibit high sensitivity to high
intrinsic noise values, except the mutual information dynamics, which is more resistant than that of
the other quantifiers.
