Opis:: We use a variational method to construct soliton solutions for systems characterized by opposing dispersion and competing nonlinearities at fundamental and second harmonics. We show that both ordinary and embedded solitons tend to gain energy when the second harmonic field becomes weaker than the first harmonic field.

Opis:: A generalized G'/G-expansion method is extended to construct exact solutions for the Gross-Pitaevskii equation with weak bias magnetic and time-dependent laser fields. Many types of exact solutions including hyperbolic function solution, trigonometric function solution and rational exact solution with parameters are obtained. In addition, soliton solutions are found.

Opis:: A generalized G'/G-expansion method is extended to construct exact solutions to the two-dimensional generalized nonlinear Schrödinger equation with distributed coefficients. Hyperbolic function solution, trigonometric function solution and rational exact solution with parameters are obtained. Selecting parameters and parameter functions properly, novel light bullet soliton solutions with or without the chirp are presented.

Opis:: The spatiotemporal collapse of the spin-dipole wave pulses of the millimeter wave range is investigated theoretically. The dispersion and the diffraction coefficients of spin-dipole wave have been calculated, when the retardation has been taken into account. It is demonstrated that YIG films are suitable for observing the wave collapse in the millimeter wave range, due to low dissipation and quite high values of dispersion and diffraction coefficients. In the hexaferrite films, despite the higher values of the dispersion and the diffraction coefficients, the dissipation prevents the formation of the spatiotemporal collapse. The additional focusing of the pulse can increase the nonlinear pulse compression. The numerical simulations have confirmed this result.
