Abstract (English)

This thesis considers the effect of collective light-matter interaction of Landau-quantized charge carriers in graphene embedded in an optical cavity. Thereby, the focus is on the controversially discussed possible existence of an equilibrium superradiant quantum phase transition in this system. This quantum effect was initially investigated within the framework of the Dicke model but it has ...

Translation of the abstract (German)

Die vorliegende Dissertation beschäftigt sich mit kollektiver Licht-Materie-Wechselwirkung von Landau-quantisiertem Ladungsträgern in Graphen, welches in einer optischen Kavität eingebettet ist. Im Fokus der Arbeit steht die Untersuchung des kontrovers diskutierten superradianten Quantenphasenübergangs im Gleichgewicht. Dieser Quanteneffekt wurde erstmals im Rahmen des Dicke Modells ...
