Casimir虫洞弱偏转角的Gauss-Bonnet定理及其阴影

Weak deflection angle by Casimir wormhole using Gauss-bonnet theorem and its shadow

Wajiha Javed, Ali Hamza, Ali Övgün

摘要:

本文利用Casimir虫洞及其阴影计算了弱偏转角。为此,我们推导出高斯光学曲率,并使用高斯-博内定理。在弱场限制下,我们求出了Casimir虫洞的偏转角.此外,我们还得到了等离子体介质存在时的弱偏转角,并考察了等离子体介质对弱偏转角的影响。此外,我们研究了Casimir虫洞的阴影,并对它们进行了绘图和讨论。当改变$a$的值时,我们显示了Casimir虫洞行为的影子。

英文摘要:

In this paper, we calculate the weak deflection angle by Casimir wormhole and its shadow. To do so, we derive the Gaussian optical curvature and use the Gauss-Bonnet theorem. Then we find the deflection angle by Casimir wormhole in weak field limits. Moreover, we obtain the weak deflection angle in the presence of plasma medium and see the effect of the plasma medium on the weak deflection angle. Moreover, we study a shadow of Casimir wormhole and we plot and discuss them. We show the shadow of Casimir wormhole's behavior when changing the value of $a$.
