The Domain Chaos Puzzle and the Calculation of the Structure Factor and Its Half-Width
Nathan Becker, Guenter Ahlers
The disagreement of the scaling of the correlation length xi between experiment and the Ginzburg-Landau (GL) model for domain chaos was resolved. The Swift-Hohenberg (SH) domain-ch…
Effect of the Centrifugal Force on Domain Chaos in Rayleigh-Bénard convection
Nathan Becker, J. D. Scheel, M. C. Cross +1
Experiments and simulations from a variety of sample sizes indicated that the centrifugal force significantly affects rotating Rayleigh-Bénard convection-patterns. In a large-aspec…
Dynamics of fluctuations below a stationary bifurcation to electroconvection in the planar nematic liquid crystal N4
Xin-liang Qiu, Guenter Ahlers
We fitted to time-correlation functions of structure factors of shadowgraph images of fluctuations…
Fluctuations of a homeotropically aligned nematic liquid crystal in the presence of an applied voltage
Sheng-Qi Zhou, Guenter Ahlers
We determined the refractive-index structure-factor from shadowgraphs of fluctuations in a layer of a homeotropically aligned nematic liquid crystal with negative diel…
The Domain Chaos Puzzle and the Moments of the Swift-Hohenberg Structure Factor
Nathan Becker, Guenter Ahlers
This paper is being extensively rewritten and will be resubmitted in a different form.
Wave-number Selection by Target Patterns and Side Walls in Rayleigh-Benard Convection
John R. Royer, Patrick O'Neill, Nathan Becker +1
We present experimental results for Rayleigh-Benard convection patterns in a cylindrical container with static side-wall forcing induced by a heater. This forcing stabilized a patt…
