The Nonequilibrium Back Reaction of Hawking Radiation to a Schwarzschild Black Hole

Figure 5

Shows the variation of the irreversible entropy production rate (red line) and the rate of entropy change of black hole (green line) with temperature difference with an initial temperature 2.73 k. We find entropy production rate is significant compared to the rate of entropy change of a black hole at a finite temperature; it also holds for other black holes with different mass.
