Far-field heat transfer and monochromatic thermal currents in a cylindrical nonreciprocal cavity
Guillem Masdemont, Julien Legendre, Georgia T. Papadakis
Breaking Kirchhoff's law of thermal radiation yields new opportunities in one-way radiative thermal transport and circuitry. We investigate its consequences in the far-field regime…

The critical role of substrates in mitigating the power-efficiency trade-off in near-field thermophotovoltaics
Kartika N. Nimje, Julien Legendre, Michela F. Picardi +2
Near-field thermophotovoltaic systems can achieve ultra-high power densities, however, this often comes at the cost of reduced efficiency. We show that this power-efficiency trade-…

Coherent Thermal Emission from Large-Scale Suspended Nanomechanical Membranes
Mitradeep Sarkar, Rajashree Haldankar, Julien Legendre +3
Thermal radiation is an abundant form of incoherent light. Generating coherent infrared light through incandescence promises a cheap alternative to the costly and epitaxially compl…
