Abstract

Thermal emission is a fundamental issue that customarily has been fueled by the developments carried out in nanophotonics. Given such a parallelism and the latest advances bringing forward the realization of temporal metamaterials, in this work we combine both topics to sketch out an original theoretical formulation for rigorously addressing thermal emission in time-modulated media. Upon this ground, we find new physics and thermal phenomena, highlighting the emergence of non-local correlations, the possibility to overcome the black-body spectrum by temporal means, as well as the role of ENZ bodies as genuine platforms to enhance thermal emission, and the conception of innovative thermal emitters dual to spatial gratings.
