Mixmaster chaos in an AdS black hole interior


QFT/Holography Seminar


21st October 2024, 2:00 pm – 3:00 pm
Fry Building, 4th Floor Seminar Room


Amongst the most fascinating behaviours to arise from Einstein’s equations is the onset of chaotic dynamics in the approach to certain cosmological singularities. This was analysed in detail in seminal work by Belinskii, Khalatnikov, Lifshitz (BKL) and others some fifty years ago. A consequence of these results is that the Schwarzschild interior solution near the singularity appears very fine-tuned and should give way for BKL-like dynamics in more generic black holes. In arxiv:2312.11622, we construct a setup that realises the so-called ‘mixmaster’ chaotic dynamics in the interior of an AdS black hole. After reviewing the work of BKL, I will describe our holographic setup and discuss the peculiar symmetries appearing in this problem.
