标题： Gravitational Instanton for Black Hole Radiation

摘要： 霍金辐射来源于存在于欧几里得黑洞几何中的欧几里得瞬子。 在考虑瞬子自身的引力场时，其作用量正好等于视界面积变化的四分之一。 这一结果同样适用于施瓦茨希尔德过程、厄库拉过程以及德西特空间中的粒子产生。 讨论了对视界热力学的意义。 显示英文摘要

摘要： Hawking radiation is derived from the existence of a euclidean instanton which lives in the euclidean black hole geometry. Upon taking into account the gravitational field of the instanton itself, its action is exactly equal to one quarter the change in the horizon area. This result also applies to the Schwinger process, the Unruh process, and particle creation in deSitter space. The implications for horizon thermodynamics are discussed.
