Mixmaster chaos in an AdS black hole interior

06.05.2024 11:00 – 12:30

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 our recent work (arxiv:2312.11622), we construct a setup that realises the so-called ‘mixmaster’ chaotic dynamics in the interior of an AdS black hole. In this talk, I will review aspects of the BKL work and the associated chaotic dynamics, describe our holographic setup and discuss the peculiar symmetries appearing in this problem.
