I A general two-dimensional analytical solution is presented for the / problem of transport current injection from a normal conductor into a I 1 superconductor and collection back into a normal conductor. The current distribution is solved for the general case which takes in the full range from essentially point source to full-width injection and collection. The current distribution also repres...

We investigate the mechanism by which topological defects form in first order phase transitions with a charged order parameter. We show how thick superconductor vortices and heavy cosmic strings form by trapping of magnetic flux. In an external magnetic field, intermediate objects such as strips and membranes of magnetic flux and chains of single winding defects are produced. At non-zero temper...

The transition metal dichalcogenide $\mathrm{Pd}{\mathrm{Te}}_{2}$ has attractive features based on its classification as a type-II Dirac semimetal and the occurrence of type-I superconductivity, providing platform for discussion topological superconductor. Our recent work revealed that superconductivity persists up to pressures $\ensuremath{\sim}2.5$ GPa superconducting temperature ${T}_{\math...

Neutrons have zero net electrical charge and can thus penetrate deeply into matter, but their intrinsic magnetic moment makes them highly sensitive to magnetic fields. These properties have been combined with radiographic (2D) and tomographic (3D) imaging methods to provide a unique technique to probe macroscopic magnetic phenomena both within and around bulk matter. Based on the spin-rotation ...

In the vicinity of type-I/type-II crossover in conventional superconductors, vortices exhibit a nonmonotonic interaction, which leads to exotic vortex matter states. We perform molecular dynamics simulations on model superconductor intertype regime. field cooled approach, we examine transition homogeneous lattice (VL) into structure consisting VL domains and Meissner-state domains. The results ...

We have investigated the superconducting properties in a single crystal of superconductor ${\mathrm{Pb}}_{2}\mathrm{Pd}$ via various techniques including, magnetization, AC transport, transverse field muon spin rotation and relaxation, heat capacity. All measurements confirm transition temperature ${T}_{C}=3.0\ifmmode\pm\else\textpm\fi{}0.1\phantom{\rule{0.28em}{0ex}}\mathrm{K}$. Electronic spe...
