Classical aspects of black hole interiors
Time: 2:00 pm

Speaker: Jorrit Kruthoff, Stanford University
Abstract: In AdS/CFT, we know that relevant operators, for instance a scalar source, can drastically change the bulk geometry. Normally one is only interested in what happens outside the horizon, but during this talk I will dive inside various black holes and discuss the effects of relevant operators. The dynamics turns out to be rather intricate with even fractal-like behaviour emerging. Furthermore, we will see that generically, Cauchy horizons will be replaced by a spacelike singularity in the presence of a relevant scalar source. This motivates a notion of ‘holographic’ cosmic censorship. This talk is based on 2006.10056 and 2008.12786.
