On December 18th, 2020, several groups of the Institute of Physics and invited external guests came together on-line for the first Scientific Workshop on Light, Matter, Interactions at the University of Graz. In total, 55 participants took part in this inspiring meeting. The one-day event featured 15 oral presentations, discussion and feedback sessions, a poster elevator pitch, and an online poster session. The workshop was held on multiple virtual and highly interactive platforms to foster scientific discussions and networking between all participants. We thank all contributors and attendees for making this event a success.
