Scientific presentations will be held orally and will be given in English (conference language) or German. Usually, presentations will have the following durations:

• For contributed talks a total of 15 minutes including discussion time and speaker change (12 min talk + 3 min discussion/speaker change).
• For invited talks a total of 30 minutes including discussion time and speaker change (25 min talk + 5 min discussion/speaker change).
• For plenary talks are 45 minutes without discussion.

For further information on the language or length of the presentation, please contact the division or working group in which you will be giving the presentation.

All lecture halls and seminar rooms are equipped with projectors (aspect ratio 16:9) and laptops, and will be opened at least 30 minutes prior to the session. We kindly ask all speakers of contributed talks to bring their presentation on a USB-stick in PDF or PowerPoint (.pptx) format and to upload it at least 15 minutes prior to the start of the session. Speakers of invited and plenary talks are also invited to follow this procedure, alternatively they may connect their own laptop via VGA or HDMI ports (if you are using VGA you will have to bring your own cable, for all other port, please provide an appropriate adapter).

We kindly ask the speakers to ensure the laptops handshake with the projectors at least 15 minutes prior to the start of the session. Service staff will be available in all lecture halls to assist with the uploading of presentations and to help with the equipment. If you need other presentation facilities please ask for availability at the information desk as soon as you arrive at the conference or better in advance via e-mail dpg24[@]physik.uni-freiburg.de.
