Probing the screening of the Casimir interaction with optical tweezers
L. B. Pires, D. S. Ether, B. Spreng +13
We measure the colloidal interaction between two silica microspheres in aqueous solution in the distance range from m to m with the help of optical tweezers. When e…
Scattering theory of the screened Casimir interaction in electrolytes
P. A. Maia Neto, F. S. S. Rosa, L. B. Pires +5
We apply the scattering approach to the Casimir interaction between two dielectric half-spaces separated by an electrolyte solution. We take the nonlocal electromagnetic response o…
Negative optical torque on a microsphere in optical tweezers
K. Diniz, R. S. Dutra, L. B. Pires +3
We show that the optical force field in optical tweezers with elliptically polarized beams has the opposite handedness for a wide range of particle sizes and for the most common co…
Double-layer force suppression between charged microspheres
D. S. Ether, F. S. S. Rosa, D. M. Tibaduiza +3
In this paper we propose a protocol to suppress double-layer forces between two microspheres immersed in a dielectric medium, being one microsphere metallic at a controlled potenti…
Probing the Casimir force with optical tweezers
D. S. Ether, L. B. Pires, S. Umrath +10
We propose to use optical tweezers to probe the Casimir interaction between microspheres inside a liquid medium for geometric aspect ratios far beyond the validity of the widely em…
