,Investigation of Fluctuations and Oscillatory States in Rayleigh-Bénard Systems by Neutron Scatterie elongated molecules have an anisotropic scattering power, i.e. the scattering depends on the orientation of the molecules relative to the (horizontal) scattering vector. There exists a well-known coupling between orientation and flow in nematics , and the onset and changes in the flow can be de

,A Rayleigh Bénard Experiment: Helium in a Small Box,gh Benard experiment, and we will study the case of a small Prandtl number fluid (0.4 < P < 1). To simplify the problem some more we shall restrict ourselves to the geometry of a small rectangular box with two or three convective rolls present. This somewhat artificial case allows us to truncate the

Period Doubling Bifurcation Route to Chaos,versal character. Although at this stage the extent at which the theory is applicable is not entirely clear, it is generally believed that it should hold for a large class of nonlinear systems, provided that phase trajectories remain confined in a phase region of adequately low dimension.

Space-Time Symmetry in Doubly Periodic Circular Couette Flow,etermined the spatial and temporal characteristics of the doubly periodic flow regime. In many cases doubly periodic flow is the final preturbulent regime, so a thorough understanding of this regime is important for understanding the onset of turbulence in such cases.

The Structure and Dynamics of Non-Stationary Taylor-Vortex Flow,the Reynolds number, the first of the nonstationary flows may either be (i) the “wavy mode”, in which azimuthal waves are superimposed upon the stationary Taylor vortices, or (ii) the “jet instability”, where the fast outward flow oscillates in axial direction. For the wide gap geometry of our appar

Pattern Formation during Crystal Growth: Theory,of dendrites and, next, at directional solidification of cellular structures and eutectics. In the first case, a study of the stability of the dendrite tip and related sidebranching deformations leads naturally to an hypothesis that the dendrite operates at or near a point of marginal instability.

Solitons in the One-Dimensional Planar Ferromagnet CsNiF3,proposed by Mikeska. In the geometry used there is no contribution to the observed scattering from the two-magnon processes which have been proposed as an alternative explanation of the central peak found in S.(q,ω)).

On the Possibility to Create Nonthermal Solitons in a One Dimensional Magnetic Sine Gordon System,em by a time dependent magnetic field. These nonthermal solitons will appear in addition to the thermally excited ones. This would open e.g. the possibility to study a nonequilibrium system and questions like soliton-soliton interaction (if the density is made high enough) and soliton diffusion (because they are created locally).
