Electron Waiting Times in Non-Markovian Quantum Transport — •Konrad Thomas and Christian Flindt — Département de Physique Théorique, Université de Genève, 1211 Genève, Switzerland

We formulate a quantum theory of electron waiting time distributions for charge transport in nano-structures described by non-Markovian generalized master equations. We illustrate our method by calculating the waiting time distribution of electron transport through a dissipative double quantum dot, where memory effects are present due to a strongly coupled heat bath. We consider the influence of non-Markovian dephasing on the distribution of electron waiting times and discuss how spectral properties of the heat bath may be detected through measurements of the electron waiting time.
