Non-Markovian effects at the Fermi-edge singularity in quantum dots    [PDF]

Katarzyna Roszak, Tomáš Novotný
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.
