Fluctuation forces à la Casimir and Van der Waals

Fluctuation forces abound in Nature and many natural processes occurring at nano- to micron-scale depend on fluctuation forces to proceed. In this talk we will look at two examples of fluctuation forces: the van der Waals and Casimir forces. I will describe how van der Waals forces arise and can provide a mechanism for molecular recognition between polarizable polymers such as double-stranded DNA. Next, I will describe a model for the Casimir force in a system containing two parallel conducting plates at high temperature, and examine the character of the Casimir force when the system is in a thermally non-equilibrated steady state.
