Quantum Circle

On various aspects of the quantum theory,
for students in the first place

A seminar of the Doppler Institute, meeting mostly on Tuesday afternoons and switching ocassionally between different places. Absence of an affiliation usually means that the speaker is a regular member of the seminar.
