Abstract

The effect of atomic spontaneous decay is considered for a two-level atom interacting with a single mode of electromagnetic field.The exact solution of the master equation is found for a chosen initial state. We study the effects of atomic decay on information and entanglement through temporal evolution of atomic quantum Fisher information, partial entropy of the atom and negativity.
