Physics of Quantum Materials Discussion Group

We meet weekly during term time for an informal discussion of relevant topics. All are welcome to join. Location: we are currently operating in hybrid model, meaning that you have a choice (whether you are leading the discussion or are just a regular participant) to join online using Teams or in person. The current room for seminars this term is Keynes Seminar Room 23 (KS23); before joining the meeting, please familiarise yourself with our instructions and guidelines.

For any queries, please contact the acting seminar organiser, Dr Jorge Quintanilla.


Members take turns for leading the meetings, either by presenting their own research or reviewing a scientific article of choice. Whiteboard presentations are preferred (in the absence of blackboards), but screen and projector could also be used. The atmosphere of the meetings is informal and so are meant to be the presentations. Occasionally the discussion is led by one of our visitors.

If you would like to volunteer for a presentation, please add your name and a topic, below, for an available date (if you do not have editing access to this page, could you please email someone who does – currently that’s all the academics listed under “Faculty” on the “People” page). “Offered” indicates the date has been proposed to a potential speaker and therefore it is not free at present. “TBA” means the slot is available. “No seminar” means there will be no DG scheduled that week (usually because of a clash with some other event).

Speakers are encouraged to email a title and abstract for their discussion to the group on the day prior to their presentation.
