The ability to control electric currents in solids laid the foundations of the modern electronics revolution, which has transformed our daily lives since the second half of the 20th century. Surprisingly, no comparable technology has yet emerged for the active control of heat flows. This project aims to develop the first building blocks of radiative thermotronics, enabling active control of radiative heat transfer. Building on a recently developed experimental platform designed to investigate many-body radiative heat transfer, we will exploit the metal–insulator phase transition of vanadium dioxide (VO₂) to actively modulate heat exchange between bodies interacting in the near field. The project will be carried out as part of a collaboration between Institut Langevin (Yannick De Wilde, ESPCI Paris, PSL University) and Laboratoire Charles Fabry – IOGS (Philippe Ben-Abdallah and Riccardo Messina).
