QED-VACUUM CONFINEMENT OF INELASTIC QUANTUM SCATTERING AT OPTICAL FREQUENCIES - A NEW PERSPECTIVE IN RAMAN-SPECTROSCOPY

The spontaneous Raman effect in C6H6 is investigated in the QED-vacuum confinement condition in the Casimir topology of an optical microcavity as a prototype inelastic quantum-scattering process at optical frequencies. The confinement determines a dramatic enhancement (over a factor of 10(3)), inhibition, and directional effects on the scattering intensity. Apart from its relevance in atomic and molecular spectroscopy, the work establishes a new perspective in the field of QED scattering involving quantum particles with any energy.
