In this letter, we investigate the changes in the quantum vacuum energy of the massless scalar field inside a Casimir cavity that orbits a wormhole. We consider a cosmological model with the isotropic form of the Morris-Thorne wormhole, embedded in the FLRW Universe. In this sense, we examine the effects of global curvature and scale factor in an instant of the cosmic history, besides the influences of the local geometry and inertial forces, on the Casimir energy density. We also study the behavior of this quantity when each plate is positioned without rotation at opposite sides of the wormhole throat, at zero and finite temperatures, taking into account the effective distance between the plates through the wormhole throat.

在这封信中，我们研究了围绕虫洞运行的卡西米尔腔内无质量标量场的量子真空能量的变化。我们考虑了一个具有各向同性形式的莫里斯-索恩虫洞的宇宙学模型，它嵌入在 FLRW 宇宙中。从这个意义上说，除了局部几何形状和惯性力的影响之外，我们还研究了宇宙历史瞬间的全局曲率和比例因子对卡西米尔能量密度的影响。我们还研究了当每个板块在虫洞喉咙的相对两侧没有旋转时，在零和有限温度下，考虑到板块之间穿过虫洞喉咙的有效距离时，这个量的行为。
