• Quantum gravity from quantum matter

    Virtual

    Title: Quantum gravity from quantum matter Abstract: We present a model of quantum gravity in which dimension, topology and geometry of spacetime are collective dynamical variables that describe the pattern […]

  • 9/10/2021 General Relativity Seminar

    Title: Asymptotic localization, massive fields, and gravitational singularities Abstract: I will review three recent developments on Einstein’s field equations under low decay or low regularity conditions. First, the Seed-to-Solution Method […]

  • Threshold phenomena in random graphs and hypergraphs

    Member Seminar Speaker: Michael Simkin Title: Threshold phenomena in random graphs and hypergraphs Abstract: In 1959 Paul Erdos and Alfred Renyi introduced a model of random graphs that is the cornerstone […]

  • 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 […]

  • Decoding Divergent Distances

    Speaker: John Stout, Harvard University Title: Decoding Divergent Distances Abstract: Motivated by a relationship between the Zamolodchikov and NLSM metrics to the so-called quantum information metric, I will discuss recent work […]

  • Simplices in the Calabi–Yau web

    Abstract: Calabi–Yau manifolds of a given dimension are connected by an intricate web of birational maps. This web has deep consequences for the derived categories of coherent sheaves on such manifolds, […]

  • Hyperbolic Geometry and Quantum Invariants

    Virtual

    Speaker: Tian Yang (Texas A&M University) Title: Hyperbolic Geometry and Quantum Invariants Abstract: There are two very different approaches to 3-dimensional topology, the hyperbolic geometry following the work of Thurston and the quantum invariants […]
