Coherent Interaction of Multiple Diffracted X-Rays in Crystals
Dedicated to Prof. Dr. G. Hildebrandt at his 60th birthday Coherent dynamical interaction in a 6-beam Borrmann diffraction experiment leading to an unusual intensity enhancement of X-ray transmission in crystals is investigated by using a synchrotron radiation source. A sharp enhanced intensity spot of two seconds of arc beamdivergence is observe 1 on the direct beam at the exact 6-beam diffrac...
متن کاملIncreasing entanglement between Gaussian states by coherent photon subtraction.
We experimentally demonstrate that the entanglement between Gaussian entangled states can be increased by non-Gaussian operations. Coherent subtraction of single photons from Gaussian quadrature-entangled light pulses, created by a nondegenerate parametric amplifier, produces delocalized states with negative Wigner functions and complex structures more entangled than the initial states in terms...
متن کاملBorn Inversion by Wavefield Backpropagation
The inverse scattering problem for an acoustic medium is formulated by using the variable background Born approximation. A constant density acoustic medium is probed by a wide-band point source, and the scattered field is observed along a curved receiver array located outside the region where the medium velocity is different from the assumed background velocity function. The solution that we pr...
