Description

Soft matter is the field of physics that concerns itself with systems that are deformable by energies on the scale of thermal fluctuations. This includes liquids, polymers, colloids, and much of biological physics. More recently, the sub-field of active matter has emerged, which studies the behavior of microswimmers and other self-propelled particles, including bacteria. While quantum phenomena are typically negligible at soft matter's relevant length scales (~1 µm), Brownian motion is important, while hydrodynamics and electrostatics play a role too. The interplay of these effects can lead to complex effects such as clustering or phase separation. In this seminar, we aim to provide an overview of the field, covering topics from hydrodynamics on small length scales, individual polymers and colloids and their dynamics all the way to the collective behavior of microswimmers and the interaction with their environment. The seminar will include analytical models that capture the essentials of the most important soft matter systems and state-of-the-art numerical methods that can solve the full physical problems.

Requirements

We expect the participants to have fundamental knowledge in classical and statistical mechanics, thermodynamics, electrodynamics, and partial differential equations.

Getting the credit points

To get the credit points for the seminar, the following criteria must be met:

• All participants must
  • make an appointment to meet with their tutor at least 8 weeks before giving the talk. At this meeting, the breadth and depth to cover the topic will be discussed, so the participant must already have taken a look at the literature provided on the website.
  • hand in a draft of their handout and presentation slides to their tutor 2 weeks before the talk
  • hand in the final version of their handout to the Hauptseminar organizer 1 week before the talk
  • give their talk at the arranged time
  • be present at all talks
  • take part in the discussions following the talks
  • give a five-minute summary of the previous week's talk on approximately one occasion (see below)
• Optional
  • Participants may give a trial talk, the location and date are then to be arranged with the tutor.
• The handout
  • consists of 8 to 10 A4 pages (5 pages for students from PHYSICS international M.Sc.) including pictures. The formatting is 11 pt font, single-spaced text.
  • describes the contents of the talk, written out in full
  • is written in English
  • must correctly and in a standard scientific style cite all sources used. Any pictures used must have a citation in the caption.
• The talk:
  • has a length of 45 minutes
  • is prepared with a slide deck in electronic form
  • is held in English
  • must cite the author underneath any picture used. Text content should not have citations, but all sources must be listed in the handout.
• The five-minute summary:
  • After each session, one student is randomly designated to open the next session
  • In the following week, that student will have five minutes to give a brief summary of the previous talk.
  • The student may reuse up to two slides from the talk they are summarizing or one slide they created themselves.
  • The slide(s) must be loaded onto the main speaker's laptop before the session starts.
  • The summarizer is also the chair of the session. Therefore, at the end of their summary, the chair will introduce the main speaker of the session, giving the speaker's name and topic and (if applicable) saying a sentence or two about how the talk connects to previous talks. Furthermore, it is the chair's job to manage the questions at the end by calling the people who raise their hands and by ensuring that the questions stay on topic.
• Participants are graded according to
  • the quality of the presentation and the handout (80 %)
  • the quality of their participation in the discussion and of the five-minute summary (20 %)
