  • Worldsheets, baby universes, and asymptotic representation theory

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

    Geometry and Mathematical Physics Seminar Speaker: Elliott Gesteau (MIT & CMSA) Title: Worldsheets, baby universes, and asymptotic representation theory Abstract: The string worldsheet can be reinterpreted as a baby universe field theory, a formalism first introduced by Coleman, Giddings and Strominger and more recently revived by Marolf and Maxfield to deal with third quantization in […]

  • Poincaré Duality in Quantum Error-Correcting Codes

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

    Member Seminar Speaker: Bowen Yang Title: Poincaré Duality in Quantum Error-Correcting Codes Abstract: Quantum information is fragile, and one of the main tools for protecting it is a family of error-correcting codes called stabilizer codes. These codes have a second life as exactly solvable models of quantum matter: the code space is the vacuum state […]

  • Extreme Diffusion

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

    Colloquium Speaker: Ivan Corwin (Columbia University) Title: Extreme Diffusion Abstract: Two hundred years ago, Robert Brown observed the statistics of the motion of grains of pollen in water. It took almost one hundred years for Einstein and others to develop an effective theory describing this motion as that of a random walker. In this talk, I will […]

  • Snake graphs and q-deformed real numbers

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

    Colloquium Speaker: James Propp (UMass Lowell) Title: Snake graphs and q-deformed real numbers Abstract: I'll present a statistical-mechanical construction of q-deformed real numbers ]_q, inspired by the q-deformed rational numbers _q of Morier-Genoud and Ovsienko. The new construction admits two equivalent formulations: one in terms of random filters in snake posets and the other in terms of […]
