  • Swampland Program

    CMSA 20 Garden Street, Cambridge, MA, United States

    During the 2021–2022 academic year, the CMSA will host a program on the so-called “Swampland.” The Swampland program aims to determine which low-energy effective field theories are consistent with nonperturbative quantum gravity considerations. Not […]

    Gromov-Witten theory of complete intersections

    Abstract: I will describe an inductive algorithm computing Gromov-Witten invariants in all genera with arbitrary insertions of all smooth complete intersections in projective space. The main idea is to show that […]

  • Quantum Geometric Aspects of Chiral Twisted Graphene Models

    Virtual

    Speaker: Jie Wang (Simons Foundation) Title: Quantum Geometric Aspects of Chiral Twisted Graphene Models Abstract: “Moire” materials produced by stacking monolayers with small relative twist angles are of intense current interest for […]

  • Curve counting on surfaces and topological strings

    Speaker: Andrea Brini, U Sheffield Title: Curve counting on surfaces and topological strings Abstract: Enumerative geometry is a venerable subfield of Mathematics, with roots dating back to Greek Antiquity and a present […]

  • 11/18/2021 Interdisciplinary Science Seminar

    Title: Amplituhedra, Scattering Amplitudes and Triangulations Abstract: In this talk I will discuss about Amplituhedra – generalizations of polytopes inside the Grassmannian – recently introduced by physicists as new geometric constructions encoding […]

    Exact Eigenstates in Non-Integrable Systems: A violation of the ETH

    Virtual

    Speaker: B. Andrei Bernevig (Princeton University) Title: Exact Eigenstates in Non-Integrable Systems: A violation of the ETH Abstract: We find that several non-integrable systems exhibit some exact eigenstates that span the energy […]
