  We study electronic transport through a quantum dot in the Fermi-edge
singularity regime, placing emphasis on its non-Markovian attributes. These are
quantified by the behavior of current noise as well as trace-distance-based
measure of non-Markovianity and found to be pronounced at low temperatures
where the interplay of many-electron correlations and quantum coherence present
in the system leads to significant quantum memory effects and non-Markovian
dynamics.
