Selfaction of Bessel wave packets in a system of coupled light guides and formation of light bullets
Abstract
The selfaction of twodimensional and threedimensional Bessel wave packets in a system of coupled light guides is considered using the discrete nonlinear Schrödinger equation. The features of the selfaction of such wave fields are related to their initial strong spatial inhomogeneity. The numerical simulation shows that for the field amplitude exceeding a critical value, the development of an instability typical of a medium with the cubic nonlinearity is observed. Various regimes are studied: the selfchanneling of a wave beam in one light guide at powers not strongly exceeding a critical value, the formation of the “kaleidoscopic” picture of a wave packet during the propagation of higherpower radiation along a stratified medium, the formation of light bullets during competition between selffocusing and modulation instabilities in the case of threedimensional wave packets, etc. In the problem of laser pulse shortening, the situation is considered when the wavefield stratification in the transverse direction dominates. This process is accompanied by the selfcompression of laser pulses in well enough separated light guides. The efficiency of conversion of the initial Bessel field distribution to two flying parallel light bullets is about 50%.

We study threedimensional (3D) Bessel lightbullet solutions of the nonlinear Schroedinger equation with a photonic lattice potential in the form of squared Bessel functions in polar coordinates, both analytically and numerically. Analytical solutions are obtained by the Hartree approximation, and numerical simulations are performed, to compare with the analytical solutions and to confirm the stability of localized solutions. The 3D spatial wave packets are built by the products of hyperbolic secant and Bessel functions. These solitons appear in different forms, such as 3D vortex solitons and multipole solitons.

Selffocusing of wave packets and envelope shock formation in nonlinear dispersive media
The selfaction of threedimensional wave packets is analyzed analytically and numerically under the conditions of competing diffraction, cubic nonlinearity, and nonlinear dispersion (dependence of group velocity on wave amplitude). A qualitative analysis of pulse evolution is performed by the moment method to find a sufficient condition for selffocusing. Selfaction effects in an electromagnetically induced transparency medium (without cubic nonlinearity) are analyzed numerically. It is shown that the selffocusing of a wave packet is accompanied by selfsteepening of the longitudinal profile and envelope shock formation. The possibility of envelope shock formation is also demonstrated for selffocusing wave packets propagating in amore » 
Formation of twodimensional nonspreading atomic wave packets in the field of two standing light waves
The formation of twodimensional nonspreading atomic wave packets produced in the interaction of a beam of twolevel atoms with two standing light waves polarised in the same plane is considered. The mechanism providing a dispersionless particle dynamics is the balance of two processes: a rapid decay of the atomic wave function away from the field nodes due to spontaneous transitions to nonresonance states and the quantum broadening of the wave packets formed in the close vicinity of field nodes. Coordinatedependent amplitudes and phases of the twodimensional wave packets were found for the j{sub g}=0 {r_reversible} j{sub e}=1 transition. (fourth seminarmore » 
Selfstabilized spatiotemporal dynamics of dissipative light bullets generated from inputs without spherical symmetry in threedimensional GinzburgLandau systems
In order to meet experimental conditions, the generation, evolution, and selfstabilization of optical dissipative light bullets from nonsphericallysymmetric input pulses is studied. Steadystate solutions of the (3+1)dimensional complex cubicquintic GinzburgLandau equation are computed using the variational approach with a trial function asymmetric with respect to three transverse coordinates. The analytical stability criterion is extended to systems without spherical symmetry, allowing determination of the domain of dissipative parameters for stable solitonic solutions. The analytical predictions are confirmed by numerical evolution of the asymmetric input pulses toward stable dissipative light bullets. Once established, the dissipative light bullet remains surprisingly robust. 
Coupled wavepackets for nonadiabatic molecular dynamics: a generalization of Gaussian wavepacket dynamics to multiple potential energy surfaces
Accurate simulation of the nonadiabatic dynamics of molecules in excited electronic states is key to understanding molecular photophysical processes. Here we present a novel method, based on a semiclassical approximation, that is as efficient as the commonly used mean field Ehrenfest or ad hoc surface hopping methods and properly accounts for interference and decoherence effects. This novel method is an extension of Heller's thawed Gaussian wavepacket dynamics that includes coupling between potential energy surfaces. By studying several standard test problems we demonstrate that the accuracy of the method can be systematically improved while maintaining high efficiency. The method is suitablemore »Cited by 6
