ZFC process in 2+1 and 3+1 multi-band superconductor

In the present work, we will study the effect of dimensionality (i.e 2 + 1 and 3 + 1) has on the different types of coupling in a two-band superconducting system, specifically for the Josephson, bi-quadratic and weak type couplings. This study will be oriented to a ZFC (Zero-Field-Cooling) process a...

Description
Summary:In the present work, we will study the effect of dimensionality (i.e 2 + 1 and 3 + 1) has on the different types of coupling in a two-band superconducting system, specifically for the Josephson, bi-quadratic and weak type couplings. This study will be oriented to a ZFC (Zero-Field-Cooling) process and we will see the effect that the variation of temperature for three special cases of the external field (fixed, H  H1) has on the order parameter ψ, phase ψ, magnetization M and free energy G(T) in these superconductors of multibands and a comparison between the behavior of these electronic and thermodynamic variables. This analysis will be carried out using the solution of time-dependent two bands Ginzburg-Landau equations (2B-TDGL). •Dimensionality (2 + 1 and 3 + 1), the type of couplings (Josephson, bi-quadratic and weak), and the temperature of the sample.•Two bands Ginzburg-Landau equations for a two-band system (2B-TDGL).
