论文摘要
我们通常表明，次阳源有效作用描述了非超级黑洞事件范围附近的探针粒子的动力学。动作中的Hagedorn温度始终等于背景黑洞的鹰温度。事实表明，插入的粒子应完全腐烂到吸引人或接近事件范围的闭合字符串。由于粒子吸收而导致的黑洞中增加的面积应解释为粒子腐烂进入的封闭弦的堕落状态的熵。在事件范围内的插入粒子和发射的闭合字符串之间的能量匹配条件下，我们检查了这种变分面积 - 内向关系，并发现在所有情况下，如果从不稳定的D0-Brane遵循第一定律的闭合弦线发射过程匹配。
We show generically that the dynamics of a probe particle near the event horizon of a non-extreme black hole is described by the tachyon effective action. The Hagedorn temperature in the action is always equal to the Hawking temperature of the background black hole. The fact suggests that the infalling particle should decay completely into gravitons or closed strings approaching the event horizon. The increased area in the black hole due to absorption of a particle should be interpreted as the entropy of degenerate states of the closed strings that the particle decays into. With the energy match condition between the infalling particle and the emitted closed strings on the event horizon, we examine this variational area-entropy relation and find that it matches in all cases if the closed string emission process from an unstable D0-brane obeys the first law.
