Constraining New Forces in the Casimir Regime Using the Isoelectronic Technique
We report the first isoelectronic differential force measurements between an Au-coated probe and two Au-coated films, made out of Au and Ge. These measurements, performed at submicron separationsExpand
Experimental investigation of the Casimir force beyond the proximity-force approximation.
The analysis of all Casimir force experiments using a sphere-plate geometry requires the use of the proximity-force approximation (PFA) to relate the Casimir force between a sphere and a flat plateExpand
Strong Casimir force reduction through metallic surface nanostructuring
The Casimir force between bodies in vacuum can be understood as arising from their interaction with an infinite number of fluctuating electromagnetic quantum vacuum modes, resulting in a complexExpand
Tests of new physics from precise measurements of the Casimir pressure between two gold-coated plates
A micromechanical torsion oscillator has been used to strengthen the limits on new Yukawa forces by determining the Casimir pressure between two gold-coated plates. By significantly reducing theExpand
Precise comparison of theory and new experiment for the Casimir force leads to stronger constraints on thermal quantum effects and long-range interactions
Abstract We report an improved dynamic determination of the Casimir pressure Pexpt between two plane plates obtained using a micromachined torsional oscillator. The main improvements in the currentExpand
Measurement of the Casimir force between dissimilar metals.
The first precise measurement of the Casimir force between dissimilar metals is reported. The attractive force, between a Cu layer evaporated on a microelectromechanical torsional oscillator and anExpand
Spatially Resolved Dynamic Correlation in the Vortex State of High Temperature Superconductors
We report transport measurements in the mixed state of YBa{sub 2}Cu {sub 3}O{sub 7{minus}{delta}} single crystals using a contact geometry which enables control of the gradient of the Lorentz forceExpand
Novel constraints on light elementary particles and extra-dimensional physics from the Casimir effect
We present supplementary information on the recent indirect measurement of the Casimir pressure between two parallel plates using a micromachined oscillator. The equivalent pressure between theExpand
Stronger Limits on Hypothetical Yukawa Interactions in the 30-8000 nm Range.
We report the results of new differential force measurements between a test mass and rotating source masses of gold and silicon to search for forces beyond Newtonian gravity at short separations. TheExpand
Dynamic Correlation in Driven Vortex Phases
We describe transport experiments where the spatial gradient of the driving Lorentz force is controlled. The velocity profiles induced by the Lorentz force gradient in the driven liquid and latticeExpand
