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

Figure 8

(a) shows the variation of the irreversible entropy production rate (red line) and the rate of entropy change of the black hole (green line) with respect to the temperature difference with an initial temperature 2.73 k. (b) shows the entropy change caused by irreversible entropy production (red line) and the entropy change of the black hole caused by radiation (green line) against the temperature difference with an initial temperature 2.73 k in time interval .
