Seminar on Aspects of Quantum Matter Theory

Im Sommersemester 2023 findet das Arbeitsgruppenseminar donnerstags von 14:00 bis 16:15 im Seminarraum 2.114 statt. Im Seminar diskutieren wir Forschungsergebnisse unserer Arbeitsgruppe, sowie neue Veröffentlichungen und Entwicklungen in folgenden Themenbereichen: Ultrakalte Quantengase, Quantensimulation, Quantencomputing, Quantenoptik, und Quantenvielteilchensysteme. Interessierte Studierende sind herzlich willkommen, am Seminar teilzunehmen!
