The method applies to a scalar field with arbitrary field parameters. We demonstrate the utility of the method by computing the renormalized stress-energy tensor for a scalar field in the Schwarzschild black hole spacetime, applying our results to discuss the null energy condition and the semiclassical backreaction.enBlack holesQuantum aspectsQuantum fieldsCurved spacetimeRenormalizationMode-sum prescription for the renormalized stress energy tensor on black hole spacetimesJournal Article10661910.1103/PhysRevD.106.0650232023-07-19https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
