Casimir effect between spherical objects: proximity-force approximation and beyond using plane waves
Tanja Schoger, Benjamin Spreng, Gert-Ludwig Ingold +1
For the Casimir interaction between two nearby objects, the plane-wave basis proves convenient for numerical calculations as well as for analytical considerations leading to an opt…
Universal Casimir interactions in the sphere-sphere geometry
Tanja Schoger, Benjamin Spreng, Gert-Ludwig Ingold +3
We study universal Casimir interactions in two configurations which appear as dual to each other. The first involves spheres described by the Drude model and separated by vacuum wh…
Universal Casimir interaction between two dielectric spheres in salted water
Tanja Schoger, Benjamin Spreng, Gert-Ludwig Ingold +2
We study the Casimir interaction between two dielectric spheres immersed in a salted solution at distances larger than the Debye screening length. The long distance behavior is dom…
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…
