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 …

We examine the ordering, pinning, and dynamics of two-dimensional pattern-forming
systems interacting with a periodic one-dimensional substrate. In the absence of the …

We report an anomalous matching effect in MoGe thin films containing pairs of circular holes
arranged in such a way that four of those pairs meet at each vertex point of a square lattice …

Phase shifter is one of the key elements of quantum electronics. In order to facilitate
operation and avoid decoherence, it has to be reconfigurable, persistent, and …

The maximum current (critical current) a type-II superconductor can transmit without energy
loss is limited by the motion of the quantized magnetic flux penetrating into a …

The effects of the coupling between two electronic condensates in two-gap mesoscopic
superconductors are studied within the Ginzburg-Landau theory using a finite difference …

Using the nonlinear Ginzburg-Landau (GL) theory, we obtain the possible vortex
configurations in superconducting thin films containing a square lattice of antidots. The …

Conformal crystals are nonuniform structures created by a conformal transformation of
regular two-dimensional lattices. We show that gradient-driven vortices interacting with a …

We present the new paradigm of critical current by design. Analogous to materials by
design, it aims at predicting the optimal defect landscape in a superconductor for targeted …
