Interplay between Superconductivity, Magnetism and Spin-dependent fields in Nanostructures
We are interested in studying systems where superconducting and magnetic ordering co-exist, e.g., in superconductor-ferromagnet hybrid structures. As it is well known, the interplay between these two phenomena leads to interesting physics as triplet superconductivity, polarization of superconductors and exotic Josephson effects. In the context of triplet superconductivity we are also interested in the study of superconducting structures with spin-orbit coupling.

Non-equilibrium Superconductivity
We are interested in the study of hybrid nanostructures with supercoducting elements under non-equilibrium conditions. Examples include: superconducting films in ac electric and magnetic fields, spin injection in superconductors and thermoelectric effects in superconductors-ferromagnetic insulators.

Spin-dependent transport in Nanostructures
Another research line of the Mesoscopic Physics Group focuses on the study of spin-dependent transport in hybrid nanostructures with intrinsic spin-dependent fields. Our goal is to explore theoretically realistic experimental setups and predict new effects related to the spin-dependent transport. Studied systems include metallic and semiconducting wires with strong spin-orbit coupling, non-centrosymmetric superconductors and superconductors in spin-dependent fields.

Transport in carbon based materials
We are particularly interested in studying the effect of spin-orbit interaction on the quantum transport properties of carbon based materials as single-layer, bi-layer graphene and carbon nanotubes.

Electron injection in one-dimensional conductors
We are interested in the problem of the electron injection in one-dimensional conducting systems as carbon nanotubes and quantum wires. Our goal is the determination of properties of the conductor via local scanning tunneling measurements.
