Dynacom : a new Franco-Japanese research laboratory

The CNRS, the Université de Rennes 1 and the University of Tokyo made the creation of Dynacom official on 4 October 2022 in Tokyo. The result of a long-standing collaboration, initiated in 1996, between Japanese teams in Tokyo and French scientists at the Rennes Institute of Physics (IPR, CNRS/Université de Rennes 1), this new international research laboratory will explore materials in all their forms (magnetism, conductivity, ferroelectricity, photonics).

Dynacom (for Dynamical Control of Materials) is an international research laboratory (IRL) between the CNRS, the University of Tokyo, and the Université de Rennes 1 and will be based on the University of Tokyo’ Hongo Campus in Tokyo, Japan. The laboratory grew out of longstanding collaboration that began in 1996 between the Japanese teams from Tokyo and French teams from the Institute of Physics of Rennes (IPR, CNRS/Université de Rennes 1), including Eric Collet, an academic at Université de Rennes 1 and the IPR, and now the deputy director of the IRL.

With joint research, the exchange of students and professors, and study trips over the last 26 years, scientists have used the full range of international collaboration tools offered by the CNRS, l’Université de Rennes 1, and the University of Tokyo, including the creation of the IM-LED,International Research Project (IRP) in 2016. A new stage began today with the creation of an IRL, which highlights this emblematic and strategic collaboration. Also involved in the Dynacom laboratory will be Tokyo Institute of Technology, Tohoku University, and Kyoto University in Japan, along with Nantes Université in France.

The development of new functionalities for technological materials

Dynacom’s research activities focus on the development of new functionalities for technological materials. The goal is to drive materials in out-of-equilibrium conditions by using light and/or electrical fields to control various physical properties such as ferroelectricity, magnetism, conductivity, and optical properties, with photonic applications. Different ways of acting on materials will be developed, based on the control of electrons, phonons, and elastic deformations, with a multi-scale approach ranging from molecules to materials.

This international cooperation enjoys the expertise of partners in advanced materials synthesis, as well as the development of cutting-edge methods to characterize and control their physical properties on ultrafast time scales. The Dynacom IRL will become part of the newly created International Research Centre (IRC)5 between the CNRS and the University of Tokyo, which will also be inaugurated on Tuesday, 4 October 2022 in Japan.

What is an IRL ?
An international associated laboratory is the result of the association of a laboratory with CNRS or Inserm as co-supervisor and a foreign laboratory. This arrangement enables the pooling of human and material resources to carry out a jointly defined project. The agreement is signed by the heads of the two organisations for a period of four years, renewable once. The Université de Rennes 1 is also a partner in the « LINK (Laboratory for Innovative Key materials and Structures), an international CNRS-St-Gobain research laboratory hosted by the National Institute of Material Sciences (NIMS) in Tsukuba, Japan: this "mirror laboratory" is located within the Institut des sciences chimiques de Rennes (UMR CNRS 6226).
