Near-field Dressing of Thermal Emission
Victor Guillemot, Raphael Mol, Riccardo Messina +4
Radiative heat transfer at subwavelength distances is generally understood as enhanced energy exchange mediated by photon tunnelling between neighboring bodies. While near-field in…
Superballistic transport of thermal photons in confined many-body systems
Jian Dong, Junming Zhao, Philippe Ben-Abdallah +1
Ballistic transport, realized when the system size is smaller than the mean free path of energy carriers, is traditionally regarded as the ultimate limit for energy transfer. Here,…
Interference-Controlled Radiative Heat Transport in Time-Modulated Networks
Philippe Ben-Abdallah
We demonstrate photonic control of radiative heat transport in nanoscale networks through phase-controlled interference between elastic and inelastic Floquet scattering channels in…
Many-Body Floquet Theory for Radiative Heat Transfer in Time-Modulated Systems
Riccardo Messina, Philippe Ben-Abdallah
We develop a general theory of radiative heat exchange between dipoles with time-modulated optical properties. This framework extends fluctuational electrodynamics beyond equilibri…
Broadband directional thermal emission with anisothermal microsources
Florian Herz, Riccardo Messina, Philippe Ben-Abdallah
Thermal emission is naturally spatially incoherent and lacks directionality. Here, we demonstrate that by precisely controlling the spatial temperature distribution within a solid,…
