Magnetic skyrmions are topologically stable nanoscale particlelike objects that were
discovered in 2009. Since that time, intense research interest in the field has led to the …

We review the depinning and nonequilibrium phases of collectively interacting particle
systems driven over random or periodic substrates. This type of system is relevant to vortices …

Finite-time singularities—local divergences in the amplitude or gradient of a physical
observable at a particular time—occur in a diverse range of physical systems. Examples …

Transport studies in a Corbino disk suggest that the Bragg glass phase undergoes a first-
order transition into a disordered solid. This transition shows sharp reentrant behavior at low …

The magnetic flux line lattice in type II superconductors serves as a useful system in which to
study condensed matter flow, as its dynamic properties are tunable. Recent studies have …

The slow sedimentation of suspensions of solid particles in a fluid results in complex
phenomena that are poorly understood. For a low volume fraction (φ) of particles, long …

We present results from an extensive series of simulations and analytical work on driven
vortex lattices interacting with periodic arrays of pinning sites. An extremely rich variety of …

We report the first observation of a striking history dependence of the structure function of
vortex matter in the peak effect regime in a Nb single crystal by using small angle neutron …

Using Langevin simulations, we examine driven colloids interacting with quenched disorder.
For weak substrates the colloids form an ordered state and depin elastically. For increasing …

The problem of an ensemble of repulsive particles on a potential-energy landscape is
common to many physical systems and has been studied in multiple artificial playgrounds …
