| May 22, 2025 | 🚨 New paper on arXiv: Absolute Entropy and the Observer’s No-Boundary State We investigate Hartle and Hawking’s no-boundary proposal for observers in closed universes, finding that it is the universal maximum entropy state which realizes a recent conjecture of Edward Witten. Huge thanks to Andreas and Erez for the great collaboration! |
| May 19, 2025 | Hyaline Chen, a Princeton undergraduate physics student I had the pleasure of advising, has won the PACM Best Research Project Award for his work that culminated in our paper on fine details of quantum chaos. Congratulations, Hyaline! |
| May 14, 2025 | Geoff Penington and I have been awarded second prize in the 2025 Gravity Research Foundation Essay Contest for our paper on quantum teleportation into black holes! Our work explored the deep relationship between information and energy in quantum black holes. |
