I study quantum mechanics and gravity, with a particular focus on the AdS/CFT correspondence. At the moment, I’m interested in boundary conformal field theories, black holes, quantum information and statistical mechanics. For a short technical overview, see my thesis proposal.

#### Notes

*Maxwell’s demon goes to Vegas*(2020). Can demons playing thermodynamic slot machines violate the second law, i.e. make free energy for free? Yes! Showing this involves some neat results from the theory of martingales.*MIP* = RE*(2020). Consulting entangled provers makes you a god, in the sense that they can quickly and reliably convince you of “yes” answers to the Halting Problem. This tells us something deep about the nature of entanglement and operator algebras.*Sphere packing and the modular bootstrap*(2019). Surprisingly, throwing balls in a box constrains the lightest black holes in certain theories of quantum gravity. The connection is linear programming!*Chaos and thermalisation*(2018). In quantum mechanics, “chaotic” can mean either “looks random” or “spreads quickly”. A brief introduction to both notions.*String perturbation theory and Riemann surfaces*(2018). To paraphrase Mark Kac, propagating strings hear the shape of every Riemann surface. I explain what this means in terms of the path integral and moduli space of a string loop amplitude.*The inflationary spectrum*(2016). If you want phenomenological constraints for your crazy pet GUT, you could do worse than go outside with a microwave camera and look at the night sky. Seminar talk on perturbations in cosmological inflation.
