We have considered the processes which lead to elastic scattering between two far ultraviolet or X–ray photons while they propagate inside a solid, modeled as a simple electron gas. The new ingredient, with respect to the standard theory of photon–photon scattering in vacuum, is the presence of low–energy, nonrelativistic electron–hole excitations. Owing to the existence of two–photon vertices,...
متن کاملResonant elastic soft x-ray scattering.
Resonant (elastic) soft x-ray scattering (RSXS) offers a unique element, site and valence specific probe to study spatial modulations of charge, spin and orbital degrees of freedom in solids on the nanoscopic length scale. It is not only used to investigate single-crystalline materials. This method also enables one to examine electronic ordering phenomena in thin films and to zoom into electron...
متن کاملTwo-photon Exchange in Electron-proton Elastic Scattering: Theory Update
Recent theoretical developments in the studies of two-photon exchange effects in elastic electron-proton scattering are reviewed. Two-photon exchange mechanism is considered a likely source of discrepancy between polarized and unpolarized experimental measurements of the proton electric form factor at momentum transfers of several GeV. This mechanism predicts measurable effects that are current...
متن کاملObservables in elastic electron-deuteron scattering with two-photon exchange
The general form of the cross section as well as the polarizations of electron-deuteron elastic scattering are given. Two-photon exchange effects are analyzed. Possible signatures of the two-photon exchange effects in the electron-deuteron elastic scattering are discussed. PACS: 13.40.GP, 25.30.-c, 25.30.Bf, 24.70.+s, 13.60.Fz
متن کاملA possibility to measure elastic photon–photon scattering in vacuum
Photon–photon scattering in vacuum due to the interaction with virtual electron-positron pairs is a consequence of quantum electrodynamics. A way for detecting this phenomenon has been devised based on interacting modes generated in microwave waveguides or cavities [G. Brodin, M. Marklund and L. Stenflo, Phys. Rev. Lett. 87 171801 (2001)]. Here we materialize these ideas, suggest a concrete cav...
