Quantum many-body systems

The Q-DYNO group has a longstanding experience on the self-consistent electron dynamics in optically excited nanostructures using quantum hydrodynamics and phase-space methods (Wigner and Vlasov). Examples of systems investigated in our group include ultrafast electron transport in thin metal films, electronic breathing modes in metallic nanoparticles and nanoshells, and plasmonic excitations in fullerene molecules. We have extended the Wigner and quantum hydrodynamic approaches to include the electronic spin in a fully quantum manner. The resulting models are used to study spin-dependent effects in polarized electron gases and spin current generation in magnetic and non-magnetic nano-objects.
