Development of a high-sensitivity torsion balance to investigate the thermal Casimir force
T. Graveson, C. Rackson, W. J. Kim
We report development of a high-sensitivity torsion balance to measure the thermal Casimir force. Special emphasis is placed on experimental investigations of a possible surface el…
New experimental limits on non-Newtonian forces in the micrometer-range
A. O. Sushkov, W. J. Kim, D. A. R. Dalvit +1
We report measurements of the short-range forces between two macroscopic gold-coated plates using a torsion pendulum. The force is measured for separations between 0.7 m and 7 $…
Observation of the thermal Casimir force
A. O. Sushkov, W. J. Kim, D. A. R. Dalvit +1
Quantum theory predicts the existence of the Casimir force between macroscopic bodies, due to the zero-point energy of electromagnetic field modes around them. This quantum fluctua…
Potential contributions of noncontact atomic force microscopy for the future Casimir force measurements
W. J. Kim, U. D. Schwarz
Surface electric noise, i.e., the non-uniform distribution of charges and potentials on a surface, poses a great experimental challenge in modern precision force measurements. Such…
Surface Contact Potential Patches and Casimir Force Measurements
Woo-Joong Kim, A. O. Sushkov, Diego A. R. Dalvit +1
We present calculations of contact potential surface patch effects that simplify previous treatments. It is shown that, because of the linearity of Laplace's equation, the presence…
Measurement of the short-range attractive force between Ge plates using a torsion balance
W. J. Kim, A. O. Sushkov, D. A. R. Dalvit +1
We have measured the short-range attractive force between crystalline Ge plates, and found contributions from both the Casimir force and an electrical force possibly generated by s…
