First-principle approach to the superpositions of gravitational fields in atom interferometry
Understanding the fundamental nature of gravity at the interface with quantum theory is a major open question in theoretical physics. Recent progress in experiments has enabled probing the interaction of...

Causality and Ideal Measurements of Smeared Fields in Quantum Field Theory
The usual quantum mechanical description of measurements, unitary kicks, and other local operations has the potential to produce pathological causality violations in the relativistic setting of quantum field theory (QFT)...

Toys can't play: physical agents in Spekkens' theory
Information is physical, and for a physical theory to be universal, it should model observers as physical systems, with concrete memories where they store the information acquired through experiments and...

Bootstrapping N = 4 sYM correlators using integrability
In this talk we combine integrability and conformal bootstrap to learn about correlation functions of planar maximally supersymmetric Yang- Mills theory. Focusing on correlators of four stress-tensor multiplets, we first...

Notes on Rapid AI Progress
In this talk I'll try to summarize why AI is making such rapid progress and why I expect that it will continue, leading to enormous impacts on pretty much everything...

Phenomenological thermodynamics with multiple quantities of interest
Joint work (in progress) with Ladina Hausmann, Nuriya Nurgalieva and Renato Renner We can classify contemporary approaches to thermodynamics in roughly four camps: (1) Top-down microscopic approaches. These are for...

Localizing Information in Quantum Gravity and State-dressed Local Operators in AdS/CFT
It is well known that quantum information can be strictly localized in quantum field theory. Similarly, one can also localize information in classical gravity up to quantities like the ADM...

The holographic dual of Renyi relative entropy
The relative entropy is a measure of the distinguishability of two quantum states. A great deal of progress has been made in the study of the relative entropy between an...
