Dr. Stefan Buhmann, Albert-Ludwigs-Universität Freiburg

The quantum vacuum is governed by fluctuating fields. These virtual photons can have very real consequences such as Casimir or van der Waals forces on polarisable objects. I will show how the structure of the quantum vacuum can be altered and controlled by introducing absorbing and dispersing media and bodies. In this way, forces in colloidal, optomechanical or cavity quantum electrodynamics contexts as well as energy transfer phenomena can be engineered at will.
