Numerical Simulations
Ginsburg-Landau equations are solved by
using advanced numerical techniques in order to determine the
distribution of the order parameter and local fields in nanostructured
superconductors and S/F hybrids. Molecular dynamics simulations
are used to study vortex matter in presence of nanoengineered
periodic pinning arrays.
