Examples of glasses are abundant, yet it remains one of the phases of matter whose
understanding is very elusive. In recent years, remarkable experiments have been …

Slow relaxation occurs in many physical and biological systems.“Creep” is an example from
everyday life. When stretching a rubber band, for example, the recovery to its equilibrium …

Vortex matter in type-II superconductors is a model complex system belonging to the vast
ensemble of disordered elastic media. In all these systems, depinning occurs when an …

We study the steady state of driven elastic strings in disordered media below the depinning
threshold. In the low-temperature limit, for a fixed sample, the steady state is dominated by a …

We report investigations on the ground-state magnetic properties of the intermetallic
compound GdCu through dc magnetization measurements. GdCu undergoes first-order …

One of the central challenges in condensed matter physics is to comprehend systems that
have strong disorder and strong interactions. In the strongly localized regime, their subtle …

We study thermal effects at the depinning transition by numerical simulations of driven one-
dimensional elastic interfaces in a disordered medium. We find that the velocity of the …

As an electrode material with reported ferrimagnetic properties, the NiCo 2 O 4 film exhibits
critical electrical transport properties under a magnetic field as well as a magnetic …

We study the thermally assisted relaxation of a directed elastic line in a two-dimensional
quenched random potential by solving numerically the Edwards-Wilkinson equation and the …

We perform a scaling analysis of the mean velocity of extended magnetic domain walls
driven in ultrathin Pt/Co/Pt ferromagnetic films with perpendicular anisotropy, as a function of …
