The transport critical current in high-Tc superconducting systems is considerably limited by the microstructural characteristics of these materials [1]. Indeed, if we schematize these systems as a collection of weakly-coupled superconducting islands, we may adopt Josephson junction network models to describe their electrodynamic response. With the aid of these models one can show that the maxim...

Superconductivity in topological materials has drawn a significant interest of the scientific community as these provide hint existence Majorana fermions conceived from quantized thermal conductivity, zero-biased conduction peak and anomalous Josephson effect. In this review, we make systematic study recent advances field superconductivity. The article comprises both bulk systems well heterostr...

High pressure is very effective tool for research of discovering new phenomena and of exploring new materials. For example, some materials undergo superconducting transition under high pressure. Also, it is well known that some insulators become metallic at high pressure. Conversely, there are some singular materials in which metallic state becomes unstable for insulating state at high pressure...
