Seminar on Aspects of Quantum Matter Theory

Wegen der Coronavirus-Epidemie findet unser Arbeitsgruppenseminar im WiSe 2020/21 (bis auf weiteres) jeden Donnerstag von 14:00 bis 16:15 als Videokonferenz statt, wobei wir Zoom verwenden (siehe auch ). Das Seminar beginnt am 5.11.2020. Hierfür erhalten Sie, ab dem 5.11.2020, jeden Donnerstag vor 14:00 Uhr einen Link per email, mit dem Sie über Ihren Webbrowser oder die Zoom-App der online-Fragestunde betreten können. Sie benötigen zur Teilnahme an der Fragestunde einen Zoom-Account. Falls Sie nicht mit der Zoom-App arbeiten wollen (siehe ) sollten Sie den Browser Google Chrome verwenden. Falls Sie am Seminar teilnehmen möchten und nicht Mitglied unserer Arbeitsgruppe sind, kontaktieren Sie bitte Prof. Hofstetter per email.

Our group seminar takes place every Thursday from 14:00 to 16:15  in room 1.101. Each seminar is devoted to presenting our recent work as well as recent publications and developments in the fields of ultracold gases, quantum optics, quantum simulation and quantum many-body systems. Interested students are welcome to attend the seminar.

Please do not confuse our group seminar with the "Condensed Matter Theory Seminar", which is held each Friday at 15:15 in room 1.114.
