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.
