Electronic structure and atomistic modelisation

Several IRAMIS teams are involved in calculations of the electronic structure (ab-initio , tight binding, Hückel methods, etc...) and more generally in the modeling of matter at the atomic scale, which also includes more phenomenological methods (empirical potentials, model Hamiltonians, etc...) These modeling tools are mainly developed and used in physics (spectroscopy, transport, magnetism), chemistry (reactivity, dynamics) and for the study of materials (diffusion, growth, defects).

Nanomagnetism, spintronic and multiferroic materials

This research topic focuses on the development and study of: magnetic materials or multiferroic oxides (ferroelectricity associated with magnetism)* the magnetization dynamics in hybrid nanostructures and its coupling to the spin currents (spintronics) development of ultra-sensitive magnetic sensor and the associated modeling.

Organic and molecular electronics

With organic and molecular electronics, a data processing based on various types of nano-objects (molecules, biomolecules, nanoparticles, carbon nanotubes, graphene,...) is emerging.

Physics and life

Three research programs of the IRAMIS found an natural extension towards biology: Molecular engineering, where studies of co-operative interactions of molecules in solution found a direct extension towards studies of proteins and of the various assembly modes of biological interest molecules, Matter with high density of energy, where radiolysis, molecule radiation interactions, can be directly transposed to molecules like the ADN, Divided ultra matter, where nanostructured materials, nanophysics and biology converge.

Statistical physics and complex systems

Statistical physics and complex systems

The understanding and control of the structure, texture, composition, kinetics of evolution of materials and thus of their physical chemical or mechanical properties are a major stake in wide fields. In much cases, the materials which one wishes to use for a given application are intrinsically evolutionary. Out of equilibrium dynamics may affect the mechanic, magnetic or electric properties of a number of materials.

Energy conversion

The development of new technologies for energy implies mastering the process of conversion between the different forms (solar, thermal, chemical, electrical, mechanical, etc.), as well as storage processes: Solar energy can be directly transformed into electrical energy via the photovoltaic process and stored in accumulators. It can also be transformed directly into chemical energy (hydrogen) by photocatalysis.
