Experimental investigation of the freely cooling granular gas
C. C. Maaß, N. Isert, G. Maret +1
Using diamagnetically levitated particles we investigate the dynamics of the freely cooling granular gas. At early times we find good agreement with Haff's law, where the time scal…
Avalanches and Self-Organized Criticality in Superconductors
Rinke J. Wijngaarden, Marco S. Welling, Christof M. Aegerter +1
We review the use of superconductors as a playground for the experimental study of front roughening and avalanches. Using the magneto-optical technique, the spatial distribution of…
Dynamic roughening of the magnetic flux landscape in YBaCuO
C. M. Aegerter, M. S. Welling, R. J. Wijngaarden
We study the magnetic flux landscape in YBaCuO thin films as a two dimensional rough surface. The vortex density in the superconductor forms a self-affine structure…
Waiting-time distribution between avalanches and 1/f-noise: Experiments on a three dimensional pile of rice
C. M. Aegerter, K. A. Lőrincz, R. J. Wijngaarden
This paper has been temporarily withdrawn by the author(s). There seems to have been an error in the data analysis and we are investigating the implications and trying to alleviate…
Self-organized criticality induced by quenched disorder: experiments on flux avalanches in NbH films
M. S. Welling, C. M. Aegerter, R. J. Wijngaarden
We present an experimental study of the influence of quenched disorder on the distribution of flux avalanches in type-II superconductors. In the presence of much quenched disorder,…
