[Q]: An anharmonic oscillator exploiting this effect as a microelectromechanical system component was proposed by Serry, Walliser, and Maclay. Julian Schwinger has postulated that sonoluminescence arises due to this effect, and this effect requires that bag radius and mass are independent under a combination of the Skyrmion and MIT models, the chiral bag model of the nucleon. One setup for measuring it attached a polystyrene sphere to an atomic force microscope, and Lamoreaux used a torsional pendulum to achieve the first precise measurements of this effect. This force may produce pressures as large as an atmosphere at a separation of ten nanometers. For 10 points, name this effect arising from zero-point energy, described by the attraction or repulsion due to virtual photons between two close uncharged metallic sheets in a vacuum.
