PHY391 Proseminar Theoretische Physik

General theme: exploring the connections between high-energy and condensed matter physics.

The talks present a selection of topics in theoretical physics which are relevant to both high-energy/particle physics and condensed matter physics at the same time. Theories with impact on such disconnected fields are of particular importance and span invisible bridges between the high- and low-energy frontiers of physics, revealing the beauty behind truly fundamental descriptions of nature.


General Information


Monday 11:00 - 12:00 as a zoom meeting (

Assignments of the Themes: Monday 17.2.2020.

The various themes will be presented and possibly assigned during the first lecture. Students unable to attend the lecture should contact T. Neupert as soon as possible.

Due to the no-classroom policy, we ask each presenter to provide a video recording of their talk as a video file. It can be recorded with, for instance as a video and a screen recording, on which slides will be presented. The podcasts last 25-30 minutes and should be in English. Please send the file (for instance as a dropbox link) at the latest on the Sunday evening before your assigned date to your supervising TA. You are not required to prepare a handout anymore. The link to the video will be in the table below.

We will then convene in a zoom meeting at 11 am each Monday to discuss the subject. It is expected that you have watched the podcasts by that time. Please also think about one question each for at least one of the talks of that day. The zoom meeting will then be used to ask these questions to the presenting students.  Attending at least 80% of the zoom meetings along with the questions is, in addition to giving your talk (podcast), the prerequisite for passing the module.

Necessary conditions for passing the module PHY391

  • Make one presentation in the form of a 30 min video podcast
  • Take part in at least 80% of the presentations by other students.
