It is based on the combination of the scattering theory and the fluctuational electrodynamics approach in many-body systems. By making a Landauer-like formulation of the heat transfer problem, explicit formulas for the energy transmission coefficients between two distinct slabs as well as the self-coupling coefficients are derived and expressed in terms of the reflection and transmission coefficients of the single bodies. We also show how to calculate local equilibrium temperatures in such systems. An analogous formulation is introduced to quantify momentum transfer coefficients describing Casimir-Lifshitz forces out of thermal equilibrium. Forces at thermal equilibrium are readily obtained as a particular case. As an illustration of this general theoretical framework, we show on three-body systems how the presence of a fourth slab can impact equilibrium temperatures in heat-transfer problems and equilibrium positions resulting from the forces acting on the system. %G English %2 https://hal.science/hal-01517943/document %2 https://hal.science/hal-01517943/file/41-PRB_95_205404_2017.pdf %L hal-01517943 %U https://hal.science/hal-01517943 %~ IOGS %~ CNRS %~ UNIV-PSUD %~ PARISTECH %~ LCFIO %~ LCF_NAPHEL %~ L2C %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ IOGS-SACLAY %~ MIPS %~ UNIV-MONTPELLIER %~ GS-ENGINEERING %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ UM-2015-2021
