We study dynamical processes in coherently coupled atomic Bose–Einstein condensates. Josephson effects in ring-shaped and dumbbell geometries are theoretically investigated. Conditions for observation of the Josephson effect ...

Conditions for formation of two- and three-dimensional localized envelope soliton-like structures in plasmas are investigated. These structures are described by modified nonlinear Schrцdinger equation, including higher ...

Stationary self-focusing of whistler waves, which propagate along magnetic field with frequencies below half electron-cyclotron frequency is considered in the framework of two-dimensional generalized nonlinear Schroedinger ...
