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.
- Microstate distinguishability, quantum complexity, and the ETH (2020). Ning Bao, Jason Pollack, DW, Elizabeth Wildenhain. arXiv: 2009.00632.
- BCFT entanglement entropy at large central charge and the black hole interior (2020). James Sully, Mark Van Raamsdonk, DW. arXiv: 2004.13088.
- Eigenstate thermalization and disorder averaging in gravity (2020). Jason Pollack, Moshe Rozali, James Sully, DW. PRL, 125:021601. arXiv: 2002.02971.
- Brane dynamics from the first law of entanglement (2019). Sean Cooper, Dominik Neuenfeld, Moshe Rozali, DW. JHEP, 2020:23. arXiv: 1912.05746.
- Information radiation in BCFT models of black holes (2019). Moshe Rozali, James Sully, Mark Van Raamsdonk, Christopher Waddell, DW. JHEP, 2020:4. arXiv: 1910.12836.
- Black hole microstate cosmology (2018). Sean Cooper, Moshe Rozali, Brian Swingle, Mark Van Raamsdonk, Christopher Waddell, DW. JHEP, 2019:65. arXiv: 1810.10601.
- 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.
