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.

  • Classification and Construction of crystalline topological superconductors and insulators in interacting fermion systems

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Quantum Matter Seminar Speaker: Zhengcheng Gu, Chinese University of Hong Kong Title: Classification and construction of crystalline topological superconductors and insulators in interacting fermion systems Abstract: The construction and classification of crystalline symmetry protected topological (SPT) phases in interacting bosonic and fermionic systems have been intensively studied in the past few years. Crystalline SPT phases […]

  • Going to the other side …. in algebra, topology, and maybe physics

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Quantum Field Theory and Physical Mathematics Speaker: Sergei Gukov (Caltech) Title: Going to the other side .... in algebra, topology, and maybe physics Abstract: Inspired by Eugene Wigner's reflections on the 'unreasonable effectiveness of mathematics in the natural sciences,' this talk is about the surprising and pervasive role of a peculiar phenomenon that, a priori, […]

  • Holography and Regge Phases at Large U(1) Charge

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Giulia Fardelli, Boston University Title: Holography and Regge Phases at Large U(1) Charge Abstract: A single Conformal Field Theory (CFT) can have a rich phase diagram with qualitatively different emergent behaviors in a range of different regimes parameterized by the conserved charges of the theory. In this […]
