The study of optical vortices is a traditional research activity of our team. This year, several important projects have been completed, such as the prediction and analysis of parametric vortex solitons in a medium with quadratic and cubic nonlinearities (such vortices have been recently demonstrated experimentally by the group of Prof. P. Di Trapani from Italy) featured in Optics and Photonics News. Together with our colleagues from the Laser Physics Centre, we have predicted and demonstrated experimentally a new effect in the physics of vortices: the so-called nonlinear Aharonov-Bohm scattering [ Opt. Lett. 25, 123 (2000), Phys. Rev. Lett. 87, 043901 (2001) ]. This result was also chosen for the special issue "Optics in 2000" that presents summaries of the most important recent research in optics. A cover story on the physics of optical vortices (written by Yuri Kivshar and Elena Ostrovskaya) has been published in the April' 2001 issue of the Optics and Photonics News [ Opt. Photon. News 12, 24 (2001) ].
