I will review consistency conditions based on Weingarten inequalities, anomalies and large N, and clarify some […]

In my talk, I will describe how the holomorphic twist isolates the protected quantities which give SUSY QFTs […]

Quantum Matter Seminar Speaker: Liang Kong (Sustech) Title: Topological Wick Rotation and Holographic duality Abstract: I will explain a new type of holographic dualities between n+1D topological orders with a chosen boundary condition and nD (potentially gapless) quantum liquids. It is based on the idea of topological Wick rotation, a notion which was first used […]

Quantum Matter Seminar Speaker: Michele Del Zotto (Uppsala University) Title: On the six-dimensional origin of non-invertible symmetries Abstract: I will present a review about recent progress in charting non-invertible symmetries for four-dimensional quantum field theories that have a six-dimensional origin. These include in particular N=4 supersymmetric Yang-Mills theories, and also a large class of N=2 […]

Quantum Matter Seminar Speaker: Ethan Lake (MIT) Title: Insulating BECs and other surprises in dipole-conserving systems Abstract: I will discuss recent work on bosonic models whose dynamics conserves both total charge and total dipole moment, a situation which can be engineered in strongly tilted optical lattices. Related models have received significant attention recently for their interesting out-of-equilibrium dynamics, […]

Quantum Matter Seminar Speaker: Francisco Machado  (Berkeley/Harvard) Title: Kardar-Parisi-Zhang dynamics in integrable quantum magnets Abstract: Although the equations of motion that govern quantum mechanics are well-known, understanding the emergent macroscopic behavior that arises from a particular set of microscopic interactions remains remarkably challenging. One particularly important behavior is that of hydrodynamical transport; when a quantum system has a […]
