本文的主要目的有两个。(1)给出了标量场在史瓦西时空中的精确解。给出了散射态和束缚态的精确波函数。除了精确解外,我们还提供了束缚态特征值和散射相移的显式近似表达式。(2)利用精确解,给出了大质量标量场视界上不连续跳跃的直接计算,而在文献中,这种跳跃是通过解析扩展处理从渐近解得到的。(C) 2019 Elsevier Inc.版权所有。
The main aim of this paper is twofold. (1) Exact solutions of a scalar field in the Schwarzschild spacetime are presented. The exact wave functions of scattering states and bound-states are presented. Besides the exact solution, we also provide explicit approximate expressions for bound-state eigenvalues and scattering phase shifts. (2) By virtue of the exact solutions, we give a direct calculation for the discontinuous jump on the horizon for massive scalar fields, while in literature such a jump is obtained from an asymptotic solution by an analytic extension treatment.
