Nonlinear diffraction of light beams propagating in photorefractive media with embedded reflecting wire
E. G. Khamis, A. Gammal, G. A. El +2
The theory of nonlinear diffraction of intensive light beams propagating through photorefractive media is developed. Diffraction occurs on a reflecting wire embedded in the nonline…

Oblique dark solitons in supersonic flow of a Bose-Einstein condensate
G. A. El, A. Gammal, A. M. Kamchatnov
In the framework of the Gross-Pitaevskii mean field approach it is shown that the supersonic flow of a Bose-Einstein condensate can support a new type of pattern--an oblique dark s…
