Killing horizons: Negative temperatures and entropy super-additivity

Many discussions in the literature of spacetimes with more than one Killing horizon note that some horizons have positive and some have negative surface gravities, but assign to all a positive temperature. However, the first law of thermodynamics then takes a nonstandard form. We show that if one re...
