Today

During 2025–26, the CMSA will host a seminar on Quantum Field Theory and Physical Mathematics, organized by Robert Moscrop, Ahsan Khan, Chuck Doran, and Keyou Zeng.

This seminar series, a successor to the Quantum Matter Seminar, focuses on all aspects of quantum field theory and its associated mathematics.

The seminar will take place on Mondays from 3:00–4:00 pm.

To receive seminar announcements, please subscribe to the mailing list.

The schedule will be updated as talks are confirmed.
