A Full Counting Statistics with the 2nd-order-von-Neumann approach — •Philipp Zedler1, Tomáš Novotný2, Clive Emary1, and Tobias Brandes1 — 1Technische Universität Berlin — 2Univerzita Karlova v Praze
We formulate a (Non-Markovian) master equation with counting fields which generalizes the 2nd-order-von-Neumann approximation. The approach can also be considered as a resonant tunneling approximation in real time diagramatics or can be derived using Liouvillian perturbation theory. We apply the formalism to the well-understood single resonant level model to make statements about its accuracy in the presence of counting fields.
