Lehrveranstaltungen im Wintersemester 2022/23

Seminar: Statistical Physics

Date and Location:

Philosophenweg 12, R106

Tuesday 9-11

The seminar starts at Tuesday, October 25 with a preliminary session. Since Tuseday, November 1 is holiday, the talks start at November 8. For a preliminary time table, see below.

Abstract

The main part of this seminar will deal with strongly correlated systems and phase transitions.

The seminar will be held in English

Each talk shall be hold by one or preferably two students. The total time of a talk is 90 minutes, but we need time for questions, discussions, etc.. Therefore, please prepare the talk for 60 minutes.

For each talk, a tutor will be available.

You may use the whatever means of presentation may be suitable. Please prepare a summary of your talk, three to four pages, for the other participants, where you mention as well the literature you used.

Please provide, if possible, the mathematical background of your talk. Often in statistical physics proofs for certain statements are known. You should present the theorem and its preconditions. You may sketch the proof if this is important and understandable for the participants.

Please contact me if you are interested in one of the topics. You may also propose a topic you like to present that is not on this list, I will put it on the list if it fits.

The topics are in most cases too large for a 60 minutes talk, therefore feel free to specialise to a certain subtopic you are interested in. Its your talk, therefore you are setting the focus.

If you have questions, just send me an email.

Here is a preliminary timetable with dates and topics. The sequence of talks is more or less fix, but we may need to shift talks. Details and literature to the topics will be announced soon.
