Self-Organized Criticality and Intermittent Turbulence in an MHD Current Sheet with a Threshold Instability
Alexander J. Klimas, Vadim M. Uritsky, Maya Paczuski
We report numerical evidence of a self-organized criticality (SOC) and intermittent turbulence (IT) symbiosis in a resistive magnetohydrodynamic (MHD) current sheet model that incl…
Coexistence of Self-Organized Criticality and Intermittent Turbulence in the Solar Corona
Vadim M. Uritsky, Maya Paczuski, Joseph M. Davila +1
An extended data set of extreme ultraviolet images of the solar corona provided by the SOHO spacecraft are analyzed using statistical methods common to studies of self-organized cr…
Inter-occurrence Times in the Bak-Tang-Wiesenfeld Sandpile Model: A Comparison with the Turbulent Statistics of Solar Flares
Maya Paczuski, Stefan Boettcher, Marco Baiesi
A sequence of bursts observed in an intermittent time series may be caused by a single avalanche, even though these bursts appear as distinct events when noise and/or instrument re…
Scale-Free Magnetic Networks: Comparing Observational Data with a Self-Organizing Model of the Coronal Field
David Hughes, Maya Paczuski
We propose that the coronal magnetic field, linking concentrations on the photosphere through an interwoven web of flux, embodies a scale-free network. It arises from a self-organi…
Luminous matter may arise from a turbulent plasma state of the early universe
Per Bak, Maya Paczuski
The almost perfect uniformity of the cosmic microwave background (CMB) radiation, discovered by Penzias and Wilson in 1965 appears to present clearcut evidence that the universe wa…
