Study of the Superradiance Phenomenon in the α--attractor Potential using the Log Derivative Method
Abstract
In this article, we solved the time--independent one--dimensional Klein--Gordon equation in the presence of α--attractor potential using the Log derivative method. We calculated the reflection coefficient R and the transmission coefficient T, showing that the superradiance phenomenon is present. In order to demonstrate the accuracy of our method, we performed a comparison with the analytical solution for the hyperbolic tangent potential.
