The force acting on a polarizable nanoparticle in the quantized electromagnetic field
In this letter we derive an expression for the force acting on a small (still
macroscopic) particle in the field of the quantized electromagnetic radiation
in any arbitrary quantum state. This result unifies in one simple formula all
known expressions for the forces (i.e. van der Waals or frictional) acting on a
small particle.Comment: 5 page
On the spectral distribution of photons between planar interfaces
Using a phenomenological approach to field quantization, an expression for
the Keldysh function of photons between two planar interfaces (Casimir
geometry) is found for any stationary quantum state of the two bodies. The case
of one interface sliding against the other is considered in detail
