摘　　要：This investigation assesses the feasibility of a traversable wormhole 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 specified distances from each other.Furthermore,the impact of the generalized uncertainty principle correction is also examined.The behavior of wormhole conditions is evaluated based on the Gauss–Bonnet coupled parameter(μ)and electric charge(Q)through the electromagnetic energy density constraint.This is attributed to the fact that the electromagnetic field satisfies the characteristicρ=-pr.Subsequently,we examine the active gravitational mass of the generated wormhole geometries and explore the behavior ofμand Q concerning active mass.The embedding representations for all formulated shape functions are examined.Investigations of the complexity factor of the charged Casimir wormhole have demonstrated that the values of the complexity factor consistently fall within a particular range in all scenarios.Finally,using the generalized Tolman–Oppenheimer–Volkoff equation,we examine the stability of the resulting charged Casimir wormhole solutions.
