چکیده
We present measurements of the polarization dependencies x-ray signal photons generated by effect parametric down-conversion x rays into ultraviolet radiation. The results exhibit pronounced discrepancies with classical model for nonlinearity but qualitatively agree a recently developed quantum mechanical theory nonlinear interaction. Our work shows that reconstruction atomic scale charge distribution valence electrons in crystals using interaction between and longer wavelength radiation, as was suggested previous works, requires knowledge beam. presented this indicate methodology study properties Wannier functions crystals.

Parametric down conversion of X-ray photons.
Parametric down conversion of X-ray photons in diamond crystals was detected in two experiments, both using the phase-matching scheme first employed in the X-ray regime by Eisenberger & McCall [Phys. Rev. Lett. (1971), 26, 684-688]. The conversion events were detected by a combination of time-correlation spectroscopy and energy discrimination, using Si drift-chamber detectors. The time-correlat...

متن کاملHyperentanglement in Parametric Down-Conversion
A theory of spontaneous parametric down-conversion, which gives rise to a quantum state that is simultaneously entangled in three-dimensional wavevector and polarization, allows us to understand the unusual characteristics of fourth-order quantum interference in many experiments, including ultrafast parametric down-conversion, the speci c example illustrated in this paper. The comprehensive app...
متن کاملQuantum properties of backward parametric down - conversion
Backward parametric down-conversion, in which one of the twin beams is generated in the opposite direction with respect to the pump laser source (Fig.1a), was theoretically predicted fifty years ago, but only recently became experimentally accessible [1], due the challenges involved in the fabrication of the required submicrometer poling period. A peculiarity of this geometry is the presence of...
