Realizing a mid-infrared broadband nonreciprocal thermal emitter with a wide emission angle range is a fundamental yet challenging task, particularly without the need for an external magnetic field. Here, we propose a nonreciprocal thermal emitter operating in the mid-infrared that achieves a ...
Coherent wave control exploits the interference among multiple waves impinging on a system to suppress or enhance outgoing signals based on their relative phase and amplitude. This process inherently requires the combination of energy exchanges among the

Experimentally, we find a quantum efficiency of 0.69 ± 0.02, well beyond the SQL, by employing a flux-driven Josephson parametric amplifier and broadband thermal signals. We expect that our results allow for fundamental improvements in the detection of ultraweak microwave signals....
This dielectric layer introduces an additional degree of freedom in optimizing the nonreciprocal thermal emitter, via imposing a tunable phase to the reflected fields. The difference between absorption and emission at wavelength of $10.99~\\\mu m$ can reach 0.932 at the incident angle of 0掳. By...
