OVERVIEW

    DYNACOM (Dynamical Control of Materials) is an International Research Laboratory (IRL) between the CNRS, the University of Tokyo and University of Rennes. It is located in Hongo Campus, Tokyo, Japan. It also involves the Tokyo Institute of Technology, the Tohoku University, the Kyoto University in Japan, and the University of Nantes in France.

    DYNACOM results from a long-standing collaboration between Japan and France, started in 1996. The IM-LED International Research Project was created in 2016 to enhance this collaboration, which extends now to a higher level with the creation of the DYNACOM IRL in 2022.

    Research activities are focused on developing new functionalities of materials. The goal is to drive materials into out-of-equilibrium conditions by using light excitation and/or electric field for controlling diverse physical properties such a ferroelectricity, magnetism, conductivity or optical properties, with photonic applications.

    The DYNACOM IRL aims to develop 3 types of physical controls to drive ultra-fast, coherent and cooperative transformations of materials. These are based on various types of optical excitations using UV, visible, infrared or terahertz light. In this way, we are developing different ways for acting on materials based on control of electrons, phonons or elastic deformations, with a multiscale approach from molecules to materials.

    Our goal is to develop new processes for enhancing materials’ efficiency in response to external stimuli. This international cooperation benefits from the expertise of the partners in synthesizing advanced materials and developing advanced methods for characterizing and tuning their physical properties on ultrafast timescale.
