added the following – who would have thought we get to this point on our lifetime:
JT-gravity gives a good approximation to the AdS-factor in the near horizon geometry $AdS_2\times S^2$ of near-extremal black holes in $\geq 4$-dimensional spacetime (NSST18, MTV18).
Via the AdS/CFT-dual of JT-gravity given by random matrix theory (Stanford-Witten 19) this allows to compute genuine quantum gravity-aspects of near-extremal black holes, such as notably their microscopic black hole entropy. Computations are now under way…
Notice that near-extremal black holes have been observed in nature, by the Chandra telescope see eg here.
