Passive radiative cooling using temperature-dependent emissivity can sometimes outperform static emitters
Yeonghoon Jin, Jin-Woo Cho, Mikhail A. Kats
In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 m can reach lower temperatures compared to broadban…

Interleaved dual-species arrays of single atoms using a passive optical element and one trapping laser
Chengyu Fang, Jared Miles, Jonathan Goldwin +8
We demonstrate trapping of individual rubidium (Rb) and cesium (Cs) atoms in an interleaved array of bright tweezers and dark bottle-beam traps, using a microfabricated optical ele…
All-passive upconversion of incoherent near-infrared light at intensities down to 10 W/cm
Rabeeya Hamid, Demeng Feng, Pournima Narayanan +10
Frequency upconversion, which converts low-energy photons into higher-energy ones, typically requires intense coherent illumination to drive nonlinear processes or the use of exter…
