Summary:
We study quantum optics in the near field.
This is relevant for several different contexts:
- scanning microscopes striving for high resolution
- miniaturized traps for quantum degenerate gases
('atom chips')
- atom-surface interactions mediated by the radiation field
- mechanical effects of light at the mesoscopic scale
('Casimir effect', 'nanomechanical oscillators')
- quantum logical gates with strings of trapped ions
In these situations, the electromagnetic field and its fluctuations
(thermal and quantum) have to be described in an
inhomogeneous, macroscopic environment.
The fields show a profoundly different behaviour compared to
free space.
