Creep of superconducting vortices in the limit of vanishing temperature: A fingerprint of off-equilibrium dynamics
Mario Nicodemi, Henrik Jeldtoft Jensen
We theoretically study the creep of vortex matter in superconductors. The low temperatures experimental phenomenology, previously interpreted in terms of ``quantum tunnelling'' of…

Universal Fluctuations in Correlated Systems
S. T. Bramwell, K. Christensen, J. -Y. Fortin +7
The probability density function (PDF) of a global measure in a large class of highly correlated systems has been suggested to be of the same functional form. Here, we identify the…

Vortices Clustering: The Origin of the Second Peak in the Magnetisation Loops of High Temperature Superconductors
D. K. Jackson, M. Nicodemi, G. Perkins +2
We study vortex clustering in type II Superconductors. We demonstrate that the ``second peak'' observed in magnetisation loops may be a dynamical effect associated with a density d…
