Epoxy resin nanocomposites are widely used in high voltage direct current (HVDC) high temperature superconducting (HTS) power cable. In this paper, the DC flashover characteristics of ZnO/EP composites at both room temperature and 77K were studied. The samples were made by dispersing ZnO nanoparticles into EP resin with weight percentages of 0%, 1%, 3%, 6% and 10% respectively. The experiment...

Additive manufacturing in industrial and commercial applications has drastically changed manufacturing capabilities while expanding the materials available to cryogenic engineers. Unfortunately, the thermal properties of 3D printed materials and filled materials are not well characterized, especially at cryogenic temperatures. To fill gaps in the literature, an experimental system was...

Unlike the more common local conductance spectroscopy, nonlocal conductance can differentiate between nontopological zero-energy modes localized around inhomogeneities, and true Majorana edge modes in the topological phase. In particular, negative nonlocal conductance is dominated by the crossed Andreev reflection. Fundamentally, the effect reflects the system’s topology. In graphene, the...

The analysis of superconducting properties in the presence of spin-orbit coupling is the subject of many scientific papers published in recent years. Unfortunately, the understanding of the problem is insufficient due to the fact that the theoretical results have been obtained using too simple models.
The main purpose of the research is to derive full thermodynamic equations for...

In the framework of the Eliashberg formalism has, the tendency to create phonon – induced superconducting state at a square lattice was analyzed. We have shown unbalanced superconducting state can not be created. However, for unbalanced parameter value smaller than $γ_{C}=0.42$ the electron – phonon interaction may induce non – classical superconducting state – the thermodynamic functions...

In this work we will discuss several theories explaining the phenomena of negative magnetoresistance (magnetoconductivity) in diluted granular multilayers samples in insulating side of the Metal-Insulator Transition (MIT). These theories will be confronted with experimental measurements in order to try to provide physical explanations for these phenomena. We re-used in our modeling...

We study in this manuscript the low temperature dependence of the electrical resistivity in the insulating phase in both cases nearest neighbors hopping and variable range hopping in a holes system of high mobility in two dimensions hole gas grown on the surface (311) GaAs. The behavior of the resistivity in the insulating phase in quantum wells p-GaAs is qualitatively consistent with the...
