What is recorded here?
Chen and colleagues used a modified atomic-force microscope to measure an oscillating lateral force between aligned, corrugated gold-coated surfaces. Its phase dependence followed the corrugation period, and the authors compared its magnitude and distance dependence with a finite-conductivity Casimir calculation for their sphere–plate geometry. Their later detailed account reports the calibration, additional electrostatic-force data and a more comprehensive uncertainty analysis.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The measurement is a small lateral deflection in a particular corrugated sphere–plate setup, with electrostatic compensation and calibration; it is not a general measurement of all geometries or a working vacuum-powered machine. The absolute closest Casimir separation is inferred from the same force theory used for comparison, followed by calibrated 12 nm increments. A separate lateral-electrostatic measurement constrains contact separation but was made hours later and also uses a force model; it does not make the absolute force-law test fully independent. The initial letter quotes about 15% relative uncertainty at 95% confidence; the detailed account reports about 24% after fuller error analysis. The surface alignment and roughness assumptions apply to this setup. Earlier theory of lateral forces and prior normal Casimir measurements retain credit.
