In this project, we propose to develop the very first setup to experimentally investigate the near-field radiative heat exchanges by thermal photons in many-body systems. We will specifically address the case of micrometer-size objects for which the appropriate multipolar theoretical formalism will be developed by our collaborators (P. Ben-Abdallah and R. Messina, Labo. Charles Fabry – IOGS), to go beyond the dipole approximation suited for objects much smaller than the thermal radiation wavelength. To this end, we will :
- Install additional probes in the experimental set-up developed by the previous PhD studen ;
- Measure the near-field heat exchanges in many-body systems by means of multiple interacting SThM probes supplemented by infrared thermal radiation studies ;
- Develop a general formalism and/or numerical simulations to study the mutual radiative heat exchanges in many-body systems made of micrometer-size objects.
