Here, we leverage quantum anomalies as a powerful nonperturbative tool to calculate optical transport in these models […]

In massless QED, the classical U(1) axial symmetry is not completely broken by the ABJ anomaly. Instead, it turns […]

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 […]
