论文摘要
在本文中，我们研究了具有非线性电动力学的静态球形对称黑洞的灰体因子。为此，我们假设标量场的最小耦合，并使用klein-gordon方程找到径向方程。然后，我们将乌龟坐标应用于将该方程式转换为Schrodinger波方程，这有助于找到有效的电位。检查有效电位的行为是否有不同的耦合和电荷参数值。我们通过使用径向方程在两个地平线和宇宙学视界中找到两种解决方案。我们考虑中间方案并匹配这两种解决方案以获得灰体因子并以图形方式检查其行为。发现灰体因子与耦合常数，质量，电荷以及黑洞的半径有逆关系，并且与角动量直接关系。
In this paper, we study the greybody factor for static spherically symmetric black hole with non-linear electrodynamics. For this purpose, we assume minimal coupling of the scalar field and find the radial equation by using the Klein-Gordon equation. We then apply tortoise coordinate to convert this equation into Schrodinger wave equation which helps to find the effective potential. The behavior of effective potential is checked for different values of the coupling and charge parameters. We find two solutions in two horizons named as event and cosmological horizons by using the radial equation. We consider the intermediate regime and match these two solutions to obtain the greybody factor and examine its behavior graphically. It is found that the greybody factor has an inverse relation with the coupling constant, mass, charge as well as the radius of the black hole and has a direct relation with angular momentum.
