Nanoscaled Systems and Structures : Optical, Electronic, and Magnetic Properties

Scientific projects and objectives

The research of our group, Nanoscaled Systems and Structures : Optical, Electronic, and Magnetic Properties (S2N-POEM), is focused on a multi-scale (atomic, nanoscopic, and molecular) study of intrinsic as well as collective phenomena, both in equilibrium and out of equilibrium, of nanostructures. Our work comprises two closely connected workpackages :

  • Development of models and general techniques, microscopic and macroscopic, classical and quantum-mechanical, at equilibrium and out of equilibrium,
  • Applications :
    • Magnetization dynamics in nanoscale spin systems,
    • Light-matter interaction and transport phenomena in nanostructures, absorption and conversion of solar spectrum.

Our research activities are led in close collaboration with experiments and aim at the development of workable models and techniques that are adapted to the investigation of nanoscale spin systems. Our approaches take into account i) the intrinsic properties of the nano-object pertaining to its size, internal crystal structure, and its surface/interface, and ii) the collective properties related with the short/long range interactions between the nano-objects, deposited on a substrate or embedded in a hosting matrix.

In addition to the now well known applications in the area of information storage on magnetic media, we are also interested in new routes for efficiently converting solar and electromagnetic energy.
