The hydrogen line spectrum explained as Raman shift

In the scattered light one observes not only the frequency of the incident ray (Rayleigh scattering) but also sum and difference frequencies of the incident light frequency. The shifted frequen ...

Photon localizability - Current research interest: photon position
... It has long been claimed that there is no hermitian photon position operator with commuting components, and hence there is not a basis of localized eigenvectors. However, we have recently published papers where it is demonstrated that a family of position operators exists. Since a sum over all k’s i ...

Adiabatic creation of coherent superposition states in atomic beams
