The Electronic Structure Discussion Group (ESDG) is an informal meeting of researchers from the Cavendish Laboratory Theory of Condensed Matter (TCM) group and the Cambridge University Centre for Computational Chemistry (CUC3), together with their colleagues from the Earth Sciences (ES), Engineering (Eng) and Materials Science and Metallurgy (MSM) departments at Cambridge University. We have expanded this group in 2020 to include many members from outside Cambridge, as we are now a virtual lecture series!

ESDG meetings are intended to promote the exchange of ideas between scientists who develop or use techniques such as density functional theory, quantum Monte Carlo, or quantum chemistry methods. Suitable subjects for presentations at ESDG meetings might include the development of novel electronic structure methods with greater accuracy or wider applicability, or the application of such methods to systems of scientific or technological importance, though we do encourage talks on any topic that people think may be of general interest to such an audience. The ESDG is currently organized by Angela Harper (TCM) and Dr. Chuck Witt (Materials). Please contact them if you wish to volunteer for a talk, or if you have any questions or comments.

Each ESDG talk will last approximately 30 minutes. The talk will be research based, typically an overview of a recent or current project. It is encouraged that some emphasis is placed on current difficulties and future directions. The final slide should present on-going tasks and open questions in order to stimulate discussion.

The schedule, along with previous talks, can be found below.

ESDG meetings are typically on Wednesdays at 11:30am virtually on Zoom and the Zoom details will be emailed to the mailing list in advance. To join the mailing list, contact the organisers.
