RESEARCH INTERESTS

In my previous research I proposed and developed the model of superdiffusive spin transport as the driving mechanism for the ultrafast demagnetisation. I have also proposed a mechanism of injection of ultrashort spin-current pulses in semiconductors, which we have recently proved experimentally breaking by several orders of magnitude the previous record of injected spin current amplitude in semiconductors.
Within my group we are working on a numerical method that will allow for the time propagation of the full Boltzmann equation (transport and scattering) far from equilibrium, meaning that no population is assumed to be either at equilibrium or close to it.

Our current research focuses on the theoretical treatment of strongly-out-of-equilibrium dynamics in real materials and heterostructures. In particular we are interested in novel phenomena arising from the non trivial interplay of strongly-out-of-equilibrium transport, thermalisation dynamics and formation of transient electromagnetic fields in the ultrafast timescale. 
We are currently interested in 
- Ultrafast spin injection in semiconductors 
- Ultrafast dynamics in topological insulators and low dimensional materials
- THz radiation generation by ferromagnet/heavy metal bilayers
- THz radiation interaction with matter 
- Discontinuous Galerkin approximation of the Boltzmann-Maxwell problem for ultrafast thermalisation/transport
