Student seminars

As announced previously, there will be two student seminars connected to this course:

• Jake Gordin, Vacuum energy and Casimir effect, Nov 18, 1 pm
• Quantum fields at finite temperature, Dec 2, 1pm

Both seminars will happen on zoom at this link. I am aware of clashes with other courses, for some of you, but it would still be great if as many of you as possible can attend.  Update: the second seminar has been cancelled.
