  • Factorization Homology

    Science Center Hall E 1 Oxford Street, Cambridge, MA, United States

    Geometry and Quantum Theory Seminar Speakers: Sunghyuk Park and Vasily Krylov, Harvard CMSA Title: Factorization Homology

  • Can Transformers Reason Logically? A Study in SAT-Solving

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

    https://youtu.be/o7uac6DuzcQ New Technologies in Mathematics Seminar Speaker: Leyan Pan, Georgia Tech Title: Can Transformers Reason Logically? A Study in SAT-Solving Abstract: Transformer-based LLMs have apparently demonstrated capabilities that resembles human reasoning. In our recent work, we investigated the Boolean reasoning abilities of decoder-only Transformers equipped with Chain-of-Thought, establishing that a Transformer model can decide all […]

  • On the Coulomb branch scaling dimensions of 4d N=2 SCFTs

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

    Member Seminar Speaker: Robert Moscrop Title: On the Coulomb branch scaling dimensions of 4d N=2 SCFTs Abstract: To each four dimensional N=2 superconformal field theory of rank-r, one can associate an r-tuple of numbers given by the scaling dimensions of a special set of protected operators whose VEVs parameterise the Coulomb branch. In this talk, I will demonstrate […]

  • A simple model for universal quantum computation

    Virtual

    Freedman CMSA Seminar Speaker: Michael Freedman Title: A simple model for universal quantum computation Abstract: I’ll present joint (unpublished) work with Charlie Marcus on a surprisingly simple – and potentially practical (?)– model for universal quantum computation whose only quantum primitive is the ability to measure a pair of adjacent electrons into either singlet (spin=0) […]

  • Quantum Effects Inside Black Holes

    Foundation Seminar
    Black Hole Initiative, 20 Garden Street, Cambridge MA CMSA, 20 Garden Street, Cambridge, MA, United States

    Joint CMSA/BHI Foundation Seminar Location: BHI seminar room Speaker: Noa Zilberman, Princeton Title: Quantum Effects Inside Black Holes Abstract: Astrophysical black holes are known to be rotating. Within classical General Relativity, the simplest spacetime solution (the Kerr solution) describing a rotating black hole reveals a traversable passage through an inner horizon – which in turn […]

  • Nonlinear Bosonization of (Non-)Fermi Liquids

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

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Yi-Hsien Du (MIT) Title: Nonlinear Bosonization of (Non-)Fermi Liquids Abstract: Fermi liquid theory is a cornerstone of condensed matter physics. I will show how to formulate Fermi liquid theory as an effective field theory. In this approach, the space of low-energy states of a Fermi liquid is identified with a […]

  • CMSA Q&A Seminar: Edgar Shaghoulian

    CMSA Q&A Seminar
    Common Room, CMSA 20 Garden Street, Cambridge, MA, United States

    CMSA Q&A Seminar Speaker: Edgar Shaghoulian, UC Santa Cruz Topic: What are the main questions in quantum gravity today?

  • Joint BHI/CMSA Foundation Seminar: Quantum Criticality in Black Hole Dynamics

    Foundation Seminar
    Black Hole Initiative, 20 Garden Street, Cambridge MA CMSA, 20 Garden Street, Cambridge, MA, United States

    Joint BHI/CMSA Foundation Seminar Location: BHI Seminar Room Speaker: Uri Kol, Harvard CMSA Title: Quantum Criticality in Black Hole Dynamics Abstract: Black hole perturbation theory captures a few important effects in the dynamics of binary mergers, such as tidal deformations and the decay of ringdown modes, as well as the physics of the photon ring. […]

  • A homotopy of 2d SCFTs and an implication for Topological Modular Forms

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

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Vivek Saxena (YITP Stony Brook and NHETC Rutgers) Title: A homotopy of 2d SCFTs and an implication for Topological Modular Forms Abstract: The Segal-Stolz-Teichner conjecture states that there exists an isomorphism between deformation classes of two-dimensional N=(0,1) superconformal field theories (SCFTs) and generalized cohomology classes known as […]

  • Smooth projective fibrations over the projective line and their sections

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

    Member Seminar Speaker: Iacopo Brivio Title: Smooth projective fibrations over the projective line and their sections Abstract: Suppose $f\colon X\to \mathbf{CP}^1$ is a smooth projective fibration, is it then true that $f$ has a section? This deceptively simple result was established by Seidel and McDuff using deep methods of symplectic geometry. Alex Pieloch recently generalized this to morphisms […]

  • Topological to Gravitational Leptogenesis, via Ultra Unification 

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

    Quantum Field Theory and Physical Mathematics Seminar Speaker: Juven Wang (LIMS, Royal Institution) Title: Topological to Gravitational Leptogenesis, via Ultra Unification Abstract: We propose a new mechanism for leptogenesis, named Topological Leptogenesis, in which dark matter consists of topological order, so gapped anyon excitations decay to generate the Standard Model lepton asymmetry. Topological Leptogenesis is in […]
