Abstract

The description of superconductivity at high temperature is a problem that has recently been addressed. Transition temperature of superconductivity, $T_c$, depends on the lattice structure type, size, and room pressure. In super-lattices and low dimensional layered nanostructures, $T_c$ is increased, by increasing the complexity of the structure and internal pressures in solid lattice. In this paper, we investigate the relation between physical parameters ($\epsilon, \mu$) of matter and superconductivity properties as well as transition temperature ($T_c$), and explain the superconductivity at high temperature. In this study, a semi-classical electromagnetic description along with vortex topologic theory and quantum dynamic models with experimental data considered to justify the relation between superconductivity phenomena and magnetic monopole properties. We find that the electromagnetic energy of magnetic monopole is in agreement with vortex energy in topological theory and it can get close to thermal energy at high temperature. These models suggest the superconductivity is related to the mobile monopole or vortices. we show that the electrical permittivity ($\epsilon$) and magnetic permeability ($\mu$) of matter have a key role in the superconductive properties.
