Scaling and Commonality in Anomalous Fluctuation Statistics in Models for Turbulence and Ferromagnetism
S. C. Chapman, G. Rowlands, N. W. Watkins
Recently, Portelli et al (2003) have semi-numerically obtained a functional form of the probability distribution of fluctuations in the total energy flow in a model for fluid turbu…
The relationship between extremum statistics and universal fluctuations
Sandra Chapman, George Rowlands, Nicholas Watkins
The normalized probability density function (PDF) of global measures of a large class of highly correlated systems has previously been demonstrated to fall on a single non-Gaussian…
Enhanced Pitch Angle Diffusion due to Electron-Whistler Interactions during Disturbed Times
W Wykes, S C Chapman, G Rowlands
During periods of increased magnetospheric activity, whistler wave emissions have been observed with increased wave amplitudes. We consider a pitch angle diffusion mechanism that i…
Signatures of dual scaling regimes in a simple avalanche model for magnetospheric activity
S. C. Chapman, N. W. Watkins, G. Rowlands
Recently, the paradigm that the dynamic magnetosphere displays sandpile-type phenomenology has been advanced, in which energy dissipation is by means of avalanches which do not hav…
Enhanced Phase Space Diffusion due to Chaos in Relativistic Electron- Whistler Mode Wave Particle Interactions in Planetary Magnetospheres
W J Wykes, S. C. Chapman, G. Rowlands
The chaotic interaction between electrons and whistler mode waves has been shown to provide a mechanism for enhanced diffusion in phase space. Pitch angle diffusion is relevant for…
