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…

SRG/ART-XC discovery of pulsations from RX J0535.0-6700: another X-ray pulsar in the LMC
I. A. Mereminskiy, A. S. Gorban, Yu. S. Klein +5
Using the Mikhail Pavlinsky ART-XC onboard the SRG observatory we have detected, for the first time, X-ray pulsations with a period of ~106 s from the poorly-studied high-mass X-ra…
