    "abstract": "It is predicted that in force microscopy the quantum fluctuations responsible\nfor the Casimir force can be directly observed as temperature-independent force\nfluctuations having spectral density $9\\pi/(40\\ln(4/e)) \\hbar \\delta k$, where\n$\\hbar$ is Planck\u0027s constant and $\\delta k$ is the observed change in spring\nconstant as the microscope tip approaches a sample. For typical operating\nparameters the predicted force noise is of order $10^{-18}$ Newton in one Hertz\nof bandwidth. The Second Law is respected via the fluctuation-dissipation\ntheorem. For small tip-sample separations the cantilever damping is predicted\nto increase as temperature is reduced, a behavior that is reminiscent of the\nKondo effect.",
