In recent years, our group has been successful in the introduction of nonlinear techniques for the detection of coherent structures in magnetized fluids. In particular, we have used an approach based on Lagrangian chaos obtaining the finite time Lyapunov exponents (FTLE) of particles advected by the fluid to determine the Lagrangian coherent structures (LCS), which are separatrix that dir…
The magnetic fields observed in stars and galaxies display magnetic energy comparable to the kinetic energy of the fluids where they are embedded. This is due to the presence of dynamo mechanisms, whereby the kinetic energy is converted into magnetic energy. Dynamos and magnetic fields play a crucial role in the solar variability, with direct impact on the Earth's climate. Moreover, magne…

Magnetic fields of many astrophysical objects are sustained by convection in their interior (e.g., in the solar convective zone or the Earth's molten outer core); this mechanism of magnetic field generation is known as convective dynamo. Many spatial and temporal scales are present in astrophysical magnetic fields. To split large-scale and small-scale dynamics in the convective dynamo pro…
The most prominent feature of nonlinear dynamical systems is its extreme sensibilityto small perturbations in an appropriate parameter range, which is explained throughunstable periodic orbits making up attracting and non attraction chaotic sets. Ouraim is study this basic structures in some fundamental systems and search for theirfingerprints, with and without noise, in basic earthquake …
