A five-level induced chiral atomic medium is used to study Casimir force and energy between two identical plates made of chiral medium under the effect of tunneling. The Casimir force and energy are studied with variations of tunneling frequency, Rabi frequencies, detuning, and plate separation after the passivity condition is satisfied. The behavior of the Casimir force is studied using the Casimir–Lifshitz formula. The results reveal that coherent tunneling strongly influences both the magnitude and nature of the Casimir interaction. While changing in medium parameters such as Rabi frequencies, detuning, and plate separation influence the overall strength of the Casimir energy and force, the tunneling frequency act as the key regulator factor defining the sign of the force. At low tunneling frequencies, the Casimir force is positive, corresponding to an attractive interaction, whereas it becomes negative, at higher tunneling frequencies demonstrating a repulsive regime. This proves that coherent tunneling can reversibly switch the Casimir force between attraction and repulsion, giving a precise means of regulatory vacuum-induced interactions in chiral systems. The obtained results have potential applications in nanoscale machines, nano-switches, ultra-sensitive detectors, and laser stabilization.
