Understanding the interaction of vortices with inclusions in type-II superconductors is a
major outstanding challenge both for fundamental science and energy applications. At …

The current-carrying capacity of type-II superconductors is decisively determined by how
well material defect structures can immobilize vortex lines. In order to gain deeper insights …

Incorporating nanoparticles into superconducting materials has emerged as an efficient
route to enhance their current-carrying capability. However, a thorough understanding of …

We present theoretical and numerical investigations of vortices driven by strong dc and ac
currents in long Josephson junctions described by a nonlinear integro-differential equation …

The ability of high-temperature superconductors (HTSs) to carry very large currents with
almost no dissipation makes them irreplaceable for high-power applications. The …

We show the results of two-terminal and four-terminal transport measurements on few-layer
NbSe 2 devices at large current bias. In all the samples measured, transport characteristics …

Here we report a novel nitridation technique for transforming niobium into hexagonal Nb2N
which appears to be superconducting below 1K. The nitridation is achieved by high …

We studied the resistive state of a mesoscopic superconducting strip (bridge) at zero
external applied magnetic field under a transport electric current, J a, subjected to different …

Vortex rectifications are well known as drifting vortices along an “easy” direction when
asymmetric potential is introduced to break the inversion symmetry for the vortex motion …

Superconducting topological systems formed by a strong 3D topological insulator (TI) in
proximity to a conventional s-wave superconductor (SC) have been intensely studied, as …
