【摘要】：这篇文章主要研究二维dilaton引力理论中表观视界附近的粒子辐射。类似于高维时空的霍金辐射的粒子隧穿效应的解释,这里将采用Hamilton-Jacobi方法研究表观视界附近的隧穿效应并由此可以看出这种效应是非常普适的只要时空中存在一个局域表观视界。通过计算辐射粒子的作用量的虚部和利用WKB近似,我们将得到粒子的辐射谱和辐射的温度。更进一步,如果假设通常的温度与表面引力之间的关系成立的话,我们将直接得到表观视界的表面引力。另一方面我们将利用类光测地线方法计算稳态情形下的辐射谱和温度。
[Abstract]:This article mainly deals with the particle radiation near the apparent horizon in the two-dimensional dilaton theory of gravitation. The interpretation of the particle tunneling effect similar to the Hocking radiation in high dimensional space-time will be used to study the tunneling effect near the apparent horizon using the Hamilton-Jacobi method, and thus it can be seen that this effect is very popular as long as it is stored in time and space. In a local apparent horizon. By calculating the imaginary part of the amount of action of the radiation particle and using the WKB approximation, we will get the radiation spectrum of the particle and the temperature of the radiation. Further, if the relationship between the normal temperature and the surface gravity is assumed, we will directly get the surface gravity of the apparent horizon. On the other hand, we will The radiation spectrum and temperature in steady state are calculated by the method of optical geodesic.
