NOMAD Laboratory "Official Remote Coffee Talk"
Thirty-minute informal talks

The coffee talks take place on Mondays at 15:30 as a hybrid meeting: in person in the common room (on the first floor) in Dahlem and via Zoom on the internet. 
Please prepare coffee roughly at 15:15 and join the zoom meeting at about 15:25
Talks should be about 15 minutes long + 10-15 minutes discussion. 
Lunch talks [L] are announced individually.

Goals of a Coffee Talk:

  • Describe challenges and open questions involving your possibly ongoing and unfinished​ project(s),
  • present short reviews of relevant literature,
  • summarize and highlight aspects of your recent publications, and
  • report interesting work you saw in conferences or workshops.

Good Practices in your Coffee Talk:

  • The talk should take less than 20 minutes.
  • Invite​ the department to your talk, announcing the title or sketching the topic briefly.
  • Share the slides​ of your talk with the department members.​
  • Try to avoid​ abbreviations​ a​nd​ acronyms​ like TRPMD, MBTR etc. DFT might be ok .
  • Avoid to present talks you will present to the institute anyhow (DPG rehearsals and theory outing).
  • Try to introduce your topic in a way that colleagues from slightly different backgrounds can follow.

The coffee talks are organized by the group leader Thomas Purcell, and the group leader Christian Carbogno. Coffee talks are mainly given by PhD students in the department. Students are encouraged to apply for a slot and each student should present at least one coffee talk per year. You can contact any of us by coming to our offices or sending an e-mail to purcell@fhi-berlin.mpg.de or carbogno@fhi-berlin.mpg.de
