Abstract
We study quantum non-Markovianity in the early stage of the emission process of a two-level atom coupled to a semi-infinite waveguide, where the waveguide termination behaves like a perfect mirror. Specifically, we restrict ourselves to analysis of the process for times shorter than twice the time delay td, where td is the duration of a round trip along the atom–mirror path. We show the emergence of a threshold in the parameter space separating the Markovian and non-Markovian regions.
