The cover image represents an array of open superconductor nanostructured microtubes in a magnetic field (shown with arrows), which is perpendicular to the tubes' axes, in a transport current that flows from one edge of a slit to the other. A nontrivial topology of the screening currents in an open tube leads to the dynamic patterns of superconducting vortices that depend on the curvature, as reported by Roman Rezaev and co‐authors in article no. 1800251. A tube fabricated by the roll‐up technology is demonstrated to produce less dissipation as compared to a planar membrane under the same magnetic field and at the same transport current. The induced voltage as a function of the magnetic field provides a unique information about vortex patterns, which helps understand topology‐ and geometry‐driven effects on dissipation characteristics of nanostructured superconductor materials.
