摘要

本研究通过考察与带电卡西米尔现象相关的能量密度,评估了可穿越虫洞(WH)的可行性。我们重点关注电荷产生的电磁场以及卡西米尔源产生的负能量密度的影响。我们通过定义这种组合的能量密度,开发出了不同的形状函数。本文探讨了卡西米尔能量密度的各种配置,特别是平行板、圆柱和球体之间按指定距离放置时的能量密度。此外,本文还研究了广义不确定性原理(GUP)修正的影响。根据高斯-波奈特(GB)耦合参数($\mu$)和电荷($Q$)对 WH 条件的行为进行了评估。虽然电磁能量密度约束(NEC)。这归因于电磁场满足$\rho=-p_{r}$的特性。随后,我们检验了所生成的 WH 几何图形的有源引力质量(AGM),并探索了 $\mu$ 和 $Q$ 在有源质量方面的行为。我们研究了所有制定的形状函数的嵌入表示。对 CCWH 复杂性因子(CF)的研究表明,在所有情况下,CF 值始终处于特定范围内。最后,我们利用广义的托尔曼-奥本海默-沃尔科夫(TOV)方程,研究了所产生的带电卡西米尔虫洞(CCWH)解的稳定性。

Casimir Wormholes inspired by Electric Charge in Einstein Gauss-Bonnet gravity
This investigation assesses the feasibility of a traversable wormhole (WH) by examining the energy densities associated with charged Casimir phenomena. We focus on the influence of the electromagnetic field created by an electric charge as well as the negative energy density arising from the Casimir source. We have developed different shape functions by defining energy densities from this combination. This paper explores various configurations of Casimir energy densities, specifically those occurring between parallel plates, cylinders, and spheres positioned at a specified distance from each other. Furthermore, the impact of the Generalised Uncertainty Principle (GUP) correction is also examined. The behavior of WH conditions is evaluated based on Gauss-Bonnet (GB) coupled parameter ($\mu$) and electric charge ($Q$). Though the electromagnetic energy density constraint (NEC). This is attributed with the fact that the electromagnetic field satisfies the characteristic that is $\rho=-p_{r}$. Subsequently, we examined the active gravitational mass (AGM) of the generated WH geometries and explored the behavior of $\mu$ and $Q$ concerning active mass. The embedding representations for all formulated shape functions are examined. Investigations of the complexity factor (CF) of CCWH have demonstrated that the values of the CF consistently fall within a particular range in all scenarios. Finally, using the generalized Tolman Oppenheimer Volkoff (TOV) equation, we examine the stability of resulting charged Casimir wormhole (CCWH) solutions.
