Correlations between the thermal vibrations of two cantilevers: Validation of deterministic analysis via the fluctuation-dissipation theorem
(AIP Publishing, 2012-02-01)
We validate a theoretical approach for analyzing correlations in the fluctuations of two cantilevers in terms of a deterministic model, using the fluctuation-dissipation theorem [M. R. Paul and M. C. Cross, Phys. Rev. Lett. ...
Rheology of fluids measured by correlation force spectroscopy
(AIP Publishing, 2012-04-01)
We describe a method, correlation force spectrometry (CFS), which characterizes fluids through measurement of the correlations between the thermally stimulated vibrations of two closely spaced micrometer-scale cantilevers ...
Lubrication forces in air and accommodation coefficient measured by a thermal damping method using an atomic force microscope
(American Physical Society, 2010-05-01)
By analysis of the thermally driven oscillation of an atomic force microscope (AFM) cantilever, we have measured both the damping and static forces acting on a sphere near a flat plate immersed in gas. By varying the ...
