Seminar on Aspects of Quantum Matter Theory

 

Our group seminar takes place every Thursday at 14:00 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 15:00 in room 1.114.
