Two-Dimensional Far-Field Correlations of X-ray Photon Pairs
E. Strizhevsky, Y. Klein, R. Hartmann +9
We directly observe far-field correlations of x-ray photon pairs generated by spontaneous parametric down-conversion (SPDC). Using an energy-resolved, two-dimensional photon counti…

Controlling X-ray emission with dispersion-engineered surface plasmon polaritons
H. Aknin, Y. Klein, S. Shwartz
We propose controlling the angular and spectral distribution of hard x-ray emission by entangling x-ray photons with ultraviolet surface plasmon polaritons (SPPs) whose dispersion…

Surface Plasmon-Enhanced X-ray Ultraviolet Nonlinear Interactions
H. Aknin, O. Sefi, D. Borodin +3
X ray matter interactions are intrinsically weak, and the high energy and momentum of X rays pose significant challenges to applying strong light matter coupling techniques that ar…
