Variations of the Lifshitz-van der Waals force between metals immersed in liquids

摘要

We present a theoretical calculation of the Lifshitz-van der Waals forcebetween two metallic slabs embedded in a fluid, taking into account the changeof the Drude parameters of the metals when in contact with liquids of differentindex of refraction. For the three liquids considered in this work, water,$CCl_3F$ and $ CBr_3F$ the change in the Drude parameters of the metal imply adifference of up to 15% in the determination of the force at short separations.These variations in the force is bigger for liquids with a higher index ofrefraction.
