Topic | Computing Casimir Forces in Arbitrary Geometries in the Time Domain |
Abstract: | Casimir forces arise due to vaccum fluctuations of the electromagnetic field and are believed to play a role in the physics of micro-electromechanical systems. I will describe a computational approach to computing Casimir forces in arbitrary geometries that exploits standard techniques from classical electromagnetism. I will describe the conceptual development of a time-domain method that allows researchers to employ free and of-the-shelf finite-difference time-domain codes without requiring any modification. I finish by providing examples of the kinds of effects that can arise in complicated structures, which we study using our numerical methods. |
