The theory of entanglement-assisted quantum metrology
The quantum Fisher information (QFI) measures the amount of information that a quantum state carries about an unknown parameter. Given a quantum channel, its entanglement-assisted QFI is the maximum QFI...

Integrability and Asymptotic Phenomena in Stochastic Vertex Models
In this talk we describe a systematic way of producing stochastic solutions to the Yang-Baxter equation from a “base solution” that is not necessarily stochastic. This gives rise to a...

TBAExtended actions, edge modes, and entanglement entropy
In this talk I will discuss some recent results on boundary degrees of freedom (or edge modes), and their description via an extended phase space structure containing extra boundary fields...

Entropy Variations and Light Ray Operators from Replica Defects
We study the defect operator product expansion (OPE) of displacement operators in free and interacting conformal field theories using replica methods. We show that as n approaches 1 a contact...

Causal Inference in Healthcare
Causal reasoning is vital for effective reasoning in science and medicine. In medical diagnosis, for example, a doctor aims to explain a patient’s symptoms by determining the diseases causing them...

The entropy of Hawking radiation
We will review the gravitational formula for fine grained entropy. We will discuss how it applies to an evaporating black hole and how we can compute the entropy of Hawking...

Inferring dark matter velocities from simulations and Gaia data
High resolution hydrodynamic simulations of galaxy formation are powerful tools, which can provide important information on the properties of the dark matter halo. Combined with the information obtained from the...

3d A-twist and analytic continuation of path integrals
I will review the relation between the A twist of 3d N=4 gauge theories and the conformal blocks/chiral cohomology of 2d chiral algebras.

Conformal geometry of random surfaces in 2D quantum gravity
From a probabilistic perspective, 2D quantum gravity is the study of natural probability measures on the space of all possible geometries on a topological surface. One natural approach is to...
