For two-dimensional condensates, we introduce patterns formed by intersection of domain-walls (DWs) between immiscible species. Both symmetric and asymmetric cases are investigated, with equal or different numbers N1,2 of atoms in the two species. The case of a rotating trap is considered too....

In bistable magnetic wires, the switching field H∗ is an applied magnetic field sufficient to remagnetise a wire. The spectrum of the fluctuations of H∗ depends on temperature. We demonstrate that this effect leads to a maximum of the thermal dependence of the amplitude of the wire...

We resume the recent theoretical and experimental results which point towards a deeper comprehension of the complex dynamics of magnetic domain walls, i.e., the Barkhausen noise. In particular, we show how the theoretical framework of depinning transition is able to correctly describe the...
