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…
A diffusion model for light scattering in ejecta
J. A. Don Jayamanne, J. -R. Burie, O. Durand +2
We derive a diffusion equation for light scattering from ejecta produced by extreme shocks on metallic samples. This model is easier to handle than a more conventional model based…
Nanometer-scale Cavities for Mid-infrared Radiation via Image Phonon Polariton Resonators
Michael Klein, Yonatan Gershuni, Alisa Perutski +2
Surface-polaritons play a pivotal role in strong light-matter interactions at the nanoscale due to their ability to confine light to deep subwavelength dimensions. A promising clas…
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,…
Effect of top metallic contacts on energy conversion performances for near-field thermophotovoltaics
Youssef Jeyar, Kevin Austry, Minggang Luo +5
The design of metallic contact grids on the front side of thermophotovoltaic cells is critical since it can cause significant optical and electrical resistive losses, particularly…
