Near-horizon physics of evaporating black holes

摘要: We study massless scalar theory with the quartic self-interacting term far away from and near to evaporating spherically symmetric black holes. propose a principle of how define physical notion particle in curved space-time. Employing this definition, we compute oneloop correction self-energy coupling constant field horizon freely-falling frame. find that becomes slightly stronger horizon. 2-point function is (partially) responsible for blackhole evaporation corresponds sub-leading Feynman propagator whose pole structure leading order.
