Title: Causality in Quantum Field Theory Abstract: In 1993 , Rafael Sorkin argued that standard quantum measurement theory and relativistic causality are not compatible because of the existence of entangled quantum states . He showed this by devising experiments using entangled states which… Read More

Title: Lattice Nonlinear Schroedinger Equation: History and Open Problems Abstract: We shall review some results, applications and generalisations.Quantum inverse scattering method and algebraic Bethe Ansatz will be used. Talk – Video Talk – Slides

Title: What Numerics Tells us About Entanglement Transitions Abstract: Entanglement transitions happen when there is a sharp change in the entanglement structure of a state upon tuning a coupling constant. Examples of entanglement transitions include the transition between… Read More

Title: Generalised Symmetries, QCD3 and Naturalness Abstract: I will explain how the framework of symmetries can be extended to non-invertible operators and I will argue that some simple gauge theories in 1+1 dimensions obey such symmetries. We will… Read More

Title: Quantum Gravity and Curvature Abstract: It has taken several decades of exploring statistical models of quantum gravity (aka nonperturbative gravitational path integrals) to understand how diffeomorphism-invariance, unitarity and the presence of a causal structure can be simultaneously… Read More

Title: Differentiate Everything: a lesson from deep learning Abstract: Deep learning taught us a new way to play with computers: compose differentiable components into a computer program, then tune its parameters via gradient optimization until that program achieves… Read More
