Dynamics of Vortices in Two-Dimensional Magnetsthe classical two-dimensional anisotropic Heisenberg model with . (easy-plane) symmetry. There are two types of vortices, characterized by their polarization (a second topological charge in addition to the vorticity): Planar vortices have Newtonian dynamics (evenorder equations of motion) and exhibi

Nonlinear Fiber Optics beginning to 1961, when a ruby laser was first used to generate the second-harmonic radiation inside a crystal [.], the use ofoptical fibers as a nonlinear medium became feasible only after 1970 when fiber losses were reduced to below 20 dB/km [.]. Stimulated Raman and Brillouin scatterings in sing

Coherent Structures in Dissipative Nonlinear Optical Systems can collapse to a localized hot spot after propagating some finite distance. Here the nonlinear optical interaction is local and assumed to be instantaneous. In a wide aperture semiconductor laser, the self-focusing nonlinearity is sluggish, responding to the relatively slow motion of the total car

Solitons in Optical Media with Quadratic Nonlinearitylutions to these models is given. Included are two- and three-wave models, gap solitons, linearly coupled waveguides with an intrinsic quadratic nonlinearity,m ultidimensional “light bullets”, two-soliton bound states (which are always unstable in the usual SHG models,but may be stable in the SHG mo

2-D Breathers and Applicationscrystals of muscovite mica. In fact, it was the conjecture that some kind of quasi-one-dimensional lattice soliton was responsible for those lines which led to the discovery of this new family of lattice excitations: mobile localized breathers of longitudinal type..We explore several properties of t

Noise in Molecular Systemswill focus on simple systems constituted of particles in periodic non-symmetric potentials under the influence of non-equilibrium noise. The resulting ratchet or motor motion is manifested through nonzero persistent particle currents. These model systems are not dissimilar to motor proteins executin
