We consider an arbitrary dilaton potential such that there are black hole solutions asymptotic at infinity to the nearly AdS2 solutions of JT gravity, and such that the black hole energy and entropy are bounded below. We show that if there is a black hole solution with negative specific heat at some temperature T, then at the same temperature there is a blackhole solution with lower free energy and positive specific heat. As the temperature is increased from zero to infinity, the black hole energy and entropy increase mo ... |
