The third law of black hole mechanics asserts that it is impossible for a non-extremal black hole to become extremal in finite time (in classical General Relativity). Counterexamples were found recently: gravitational collapse of a massless charged scalar field can produce an exactly extremal Reissner-Nordstrom black hole in finite time, passing through an intermediate phase in which the...

It has often been assumed that quantum gravity effects near a macroscopic black hole horizon should be strongly suppressed due to the enormous hierarchy between the horizon scale and the Planck scale, and that any observable deviations would require highly speculative or poorly controlled non-local physics. However, it has recently become clear that this expectation can fail in a controlled...

Entanglement plays a central role in our understanding of the emergence of spacetime in holography. There is growing evidence that many holographic states have significant multiparty entanglement. I will discuss some signals of multiparty entanglement, and their behaviour in holographic states.
