Measurement of the Casimir Force between 0.2 and 8 mum: Experimental Procedures and Comparison with Theory
Giuseppe Bimonte, Benjamin Spreng, Paulo A. Maia Neto +4
We present results on the determination of the differential Casimir force between an Au-coated sapphire sphere and the top and bottom of Au-coated deep silicon trenches performed b…
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…
Casimir Interaction Between a Plane and a Sphere: Correction to the Proximity-Force Approximation at Intermediate Temperatures
Vinicius Henning, Benjamin Spreng, Paulo A. Maia Neto +1
We consider the Casimir interaction energy between a plane and a sphere of radius at finite temperature as a function of the distance of closest approach . Typical exper…
Plane-wave approach to the exact van der Waals interaction between colloid particles
Benjamin Spreng, Paulo A. Maia Neto, Gert-Ludwig Ingold
The numerically exact evaluation of the van der Waals interaction, also known as Casimir interaction when including retardation effects, constitutes a challenging task. We present…
The role of diffraction in the Casimir effect beyond the proximity force approximation
Vinicius Henning, Benjamin Spreng, Michael Hartmann +2
We derive the leading-order correction to the proximity force approximation (PFA) result for the electromagnetic Casimir interaction in the plane-sphere geometry by developing the…
Proximity force approximation and specular reflection: Application of the WKB limit of Mie scattering to the Casimir effect
Benjamin Spreng, Michael Hartmann, Vinicius Henning +2
The electromagnetic Casimir interaction between two spheres is studied within the scattering approach using the plane-wave basis. It is demonstrated that the proximity force approx…
