| Summary: | The overarching theme of the thesis are the emergent novel phenomena in two-component superconductors. My advisor in Colombia, Prof. Barba Ortega, has directed my research on two-component superconductors made of one same material, with properties spatially changed by either localized heating or nanostructuring. My advisor in Belgium, Prof. Milosevic, directed my research on samples made of two distinct superconducting materials, related to very recent experiments, with accompanying development of the theoretical model and the numerical implementation suited for high-performance computing. The principal objective of this thesis is to investigate the behavior of vortex matter under the effect of several configurations of pinning landscape with the inclusion of the enhanced surface, in several cases in this research, by using De Gennes’ boundary condition phenomenological parameter. Its effect is studied upon the vorticity, magnetic induction, Cooper pair density, magnetization and phase of the order parameter as functions of the external applied magnetic field. |
