Research carried out in the Q-Dyno group focuses on the theoretical modeling and numerical simulation of nano-scale systems composed of many interacting constituents. We study the nonlinear quantum dynamics of charges and spins in various types of nano-objects, such as thin metal films, metallic and ferromagnetic nanoparticles, large molecules, and magnetic materials. We have developed a portfolio of analytical and computational tools, including the complete N-body description for few-electron systems, mean-field-like approaches such as Hartree-Fock and density functional theory, as well as quantum hydrodynamic models. Our group is an expert on the phase-space dynamics of quantum systems, based on Wigner functions.
We are also involved in an international collaboration (GBAR), based at CERN, which studies the effect of gravity on antimatter.
The group currently consists of two permanent staff (Paul-Antoine Hervieux and Giovanni Manfredi) and several post-doctoral researchers, PhD and Master students.
