Physics Chat
The Physics Chat meeting series is intended to provide a common platform for discussions and presentations of recent developments within the condensed matter and photonics group, and is a forum for all members of the groups, from project students to group leaders.
The meeting is held fortnightly on Thursdays at 14:00. It lasts typically 1 hour, with a presentation of 30-45 minutes.
In autumn 2023, we host in-person talks at Queen's Buildings N/2.05 or Translational Research Hub (TRH) seminar room with zoom live streaming.
The zoom meeting ID is: 896 6388 5790,
