Electrically switchable Casimir forces using transparent conductive oxides
Tao Gong, Benjamin Spreng, Miguel Camacho +3
Casimir forces between charge-neutral bodies originate from quantum vacuum fluctuations of electromagnetic fields, which exhibit a critical dependence on material's electromagnetic…
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…
The Effect of Epsilon-Near-Zero (ENZ) Modes on the Casimir Interaction between Ultrathin Films
Tao Gong, Inigo Liberal, Benjamin Spreng +3
Vacuum fluctuation-induced interactions between macroscopic metallic objects result in an attractive force between them, a phenomenon known as the Casimir effect. This force is the…
Radiative energy bandgap of nanostructures coupled with quantum emitters around the epsilon-near-zero (ENZ) frequency
Tao Gong, Inigo Liberal, Miguel Camacho +3
Epsilon-near-zero (ENZ) materials have been demonstrated to exhibit unique electromagnetic properties. Here we propose the concept of radiative energy bandgap for an ENZ nanopartic…
