Abstract (English)

This thesis deals with transport in interacting transport setups by analytic and numerical means. It comprises two main parts. First, we derive a quantum master equation to compute the reduced density matrix of the central system. It is based on a superoperator formalism that allows one to work in the weak coupling regime, as well as to define diagrammatic rules that can describe higher order ...

Translation of the abstract (German)

In der vorliegenden Arbeit werden die Eigenschaften von wechselwirkenden Transportsystemen mithilfe analytischer und numerischer Methoden untersucht. Sie besteht aus zwei Teilen. Zuerst wird eine Quanten Master Gleichung hergeleitet, mit deren Hilfe man die reduzierte Dichtematrix des zentralen Systems berechnen kann. Sie bassiert auf einem Superoperator Formalismus, welcher sowohl bei schwacher ...
