Abstract: Objects around us constantly emit and absorb thermal radiation. The emission and absorption processes are governed by two fundamental radiative properties: emissivity and absorptivity. For reciprocal systems, the emissivity and absorptivity are restricted to be… read more here.

Abstract: We demonstrate nonreciprocal far-field thermal emission and nonreciprocal near-field radiative heat transfer of Weyl semimetal nanoparticles when the circular thermal emission of the particles directionally couples with the spin of the surface modes supported by… read more here.

DOI: 10.1109/lpt.2023.3274161
Abstract: Violation of Kirchhoff’s law is of fundamental importance to improve the efficiency of energy harvesting. However, experimental confirmation of breaking the balance between emissivity and absorptivity with complex designs are difficult, and previous theoretical proposals… read more here.
