Avalanche dynamics are found in many phenomena, from earthquakes to the evolution of
species. They can also be found in vortex matter when a type-II superconductor is externally …

Magnetic domain walls are topological solitons whose internal structure is set by competing
energies which sculpt them. In common ferromagnets, domain walls are known to be of …

The following chapter provides an overview of the techniques used to understand Self-
Organised Criticality (SOC) by performing computer simulations. Those are of particular …

As a step toward isolating the influence of a modulated substrate potential on dynamics and
phase transitions in two dimensions, we have studied the behavior of a monolayer of …

We present a study of the lower critical field, H c 1, of SrTi 1− x Nb x O 3 as a function of
carrier concentration with the aim of quantifying the superfluid density. At low carrier …

By combining micro-Hall probe and magneto-optical imaging techniques we have been able
to examine vortex avalanches at different locations of the ridgelike magnetic topography of …

We present a two-dimensional system that exhibits features of self-organized criticality. The
avalanches that occur on the surface of a pile of rice are found to exhibit finite size scaling in …

Superconductors are well known for their ability to screen out magnetic fields. In type-II
superconductors, as the magnetic field pressure is progressively increased, magnetic flux …

Using a magneto-optical technique we perform a quantitative analysis of magnetic flux
penetration in superconducting niobium thin films on A-plane (112¯ 0) sapphire substrates …

We investigate flux front penetration in a disordered type-II superconductor by molecular
dynamics simulations of interacting vortices and find scaling laws for the front position and …
