Many-body near-field radiative heat transfer – NBODHEAT

Submission summary

Solid bodies at different temperatures and separated by a gap exchange heat in the form of thermal photons. Up to now only the radiative exchanges between two objects had been considered. The goal of the present project is to explore the physics of radiative exchanges in near-field regime between several objects in interaction. Our goal is threefold: (i) Establish a full theoretical framework to study near-field radiative heat transfer in arbitrary many-body systems; (ii) Measure the near-field radiative heat exchanges in simple many-body systems by means of a multi-probe SThM platform; (iii) Explore the potential of many-body systems in the fields of nanoscale thermal management and heat-assisted data recording. This project is based on the complementary expertise of 5 permanent researchers from 3 different labs (Charles Fabry Laboratory, Laboratoire National d’Esssais and Langevin Institute) who have seminal contributions in the field of near-field heat transfer and in metrology.
