Fracton orders in hyperbolic space and its excitations with fractal mobility
Quantum Matter Seminar Speaker: Han Yan (Rice U) Title: Fracton orders in hyperbolic space and its excitations with fractal mobility Abstract: Unlike ordinary topological quantum phases, fracton orders are intimately […]
Motivic Geometry of Two-Loop Feynman Integrals
Member Seminar Speaker: Chuck Doran Title: Motivic Geometry of Two-Loop Feynman Integrals Abstract: We study the geometry and Hodge theory of the cubic hypersurfaces attached to two-loop Feynman integrals for generic […]
From spin glasses to Boolean circuits lower bounds – Algorithmic barriers from the overlap gap property
Speaker: David Gamarnik (MIT) Title: From spin glasses to Boolean circuits lower bounds. Algorithmic barriers from the overlap gap property Abstract: Many decision and optimization problems over random structures exhibit an apparent gap […]
Bakry-Emery theory and renormalisation
Probability Seminar Speaker: Roland Bauerschmidt (Cambridge) Title: Bakry-Emery theory and renormalisation Abstract: I will discuss an approach to log-Sobolev inequalities that combines the Bakry-Emery theory with renormalisation and present several […]

Non-invertible Symmetry Enforced Gaplessness
Quantum Matter Seminar Speaker: Ho Tat Lam (MIT) Title: Non-invertible Symmetry Enforced Gaplessness Abstract: Quantum systems in 3+1-dimensions that are invariant under gauging a one-form symmetry enjoy novel non-invertible duality symmetries encoded […]
Parity and Cobordism
Swampland Seminar Speaker: Jake McNamara (Caltech) Title: Parity and Cobordism Abstract: The swampland cobordism conjecture provides a convenient way to discuss conserved charges associated with the topology of spacetime. However, much of […]
Complete Calabi-Yau metrics: Recent progress and open problems
Speaker: Tristan Collins, MIT Title: Complete Calabi-Yau metrics: Recent progress and open problems Abstract: Complete Calabi-Yau metrics are fundamental objects in Kahler geometry arising as singularity models or "bubbles" in […]
Dynamics of active nematic defects on cones
Member Seminar Speaker: Farzan Vafa Title: Dynamics of active nematic defects on cones Abstract: In the first part of the talk, we investigate the ground-state configurations of two-dimensional liquid crystals with […]
Manifold Fitting: An Invitation to Statistics
Probability Seminar Speaker: Zhigang Yao (Harvard CMSA/National University of Singapore) Title: Manifold Fitting: An Invitation to Statistics Abstract: This manifold fitting problem can go back to H. Whitney’s work in the early […]
