Fundamental Constraints for Fundamental Theories
As our understanding of the universe and its fundamental building blocks extends to shorter and shorter distances, experiments capable of probing these scales are becoming increasingly difficult to construct. Fundamental...

Area law of non-critical ground states in 1D long-range interacting systems
The area law for entanglement provides one of the most important connections between information theory and quantum many-body physics. It is not only related to the universality of quantum phases...

Leonard Elschenbroich, cello with Alexei Grynyuk, piano
No other composer has left behind a legacy greater than Beethoven. Beethoven is everywhere - a global artist whose name needs no introduction and whose language requires no translation. In...

Holomorphic-topological twists and TFT
I'll explain the TFT perspective on holomorphic-topological twists of 3d N=4 and 4d N=2 theories, and outline some connections between the topics discussed in Justin and Davide's previous lectures, and...

Categorified sheaf theory and the spectral Langlands TQFT
It is expected that the Betti version of the geometric Langlands program should ultimately be about the equivalence of two 4-dimensional topological field theories. In this talk I will give...

The trinity of relational quantum dynamics
In order to solve the problem of time in quantum gravity, various approaches to a relational quantum dynamics have been proposed. In this talk, I will exploit quantum reduction maps...

Gapped condensation in higher categories
Idempotent (aka Karoubi) completion is used throughout mathematics: for instance, it is a common step when building a Fukaya category. I will explain the n-category generalization of idempotent completion. We...

Tensor 2-categories of Hall modules
Tensor 2-categories are expected to play a fundamental role in 4D quantum topology. The study of tensor 2-categories is still in its early stages, especially when compared to the vast...

Single-Shot-Decoding with High Thresholds in LDPC Quantum Codes with Constant Encoding Rate
It is believed that active quantum error correction will be an essential ingredient to build a scalable quantum computer. The currently favored scheme is the surface code due to its...
