Wave functionals, boundary conditions and Casimir effect
The classic Casimir effect is a force between conducting plates in pure vacuum. It can be viewed as arising from the zero-point energy of quantized fields. This force is relevant in a variety of contexts, from the compactification of higher dimensional spacetimes to the mechanical manipulation of nanoparticles. In this talk, I will focus on the geometry dependence and the contribution of edges and diffractive effects. We use an analogy with wave functionals to calculate the effects of edges and boundaries and different types of boundary conditions.
