Cs HPB This video shows the extinction coefficient of a thermal Caesium vapour with an applied magnetic field being ramped from 0 to 15000 gauss. ElecSus was used to make the data for the video which is composed of 1426 spectra each with 8000 data points ranging from -40 to 40 GHz with 10 MHz precision. The data took just under 3 minutes to calculate on a simple desktop machine. Download

Stretching in a model of a turbulent flow Using a multi-scaled, chaotic flow known as the KS model of turbulence [J.C.H. Fung, J.C.R. Hunt, A. Malik, R.J. Perkins, Kinematic simulation of homogeneous turbulence by unsteady random fourier modes, J. Fluid Mech. 236 (1992) 281–318], we investigate the dependence of Lyapunov exponents on various characteristics of the flow. We show that the KS model yields a power law relation between the Reynolds number and the maximum Lyapunov exponent, which is similar to that for a turbulent flow with the same energy spectrum. Our results show that the Lyapunov exponents are sensitive to the advection of small eddies by large eddies, which can be explained by considering the Lagrangian correlation time of the smallest scales. We also relate the number of stagnation points within a flow to the maximum Lyapunov exponent, and suggest a linear dependence between the two characteristics. Download
