First experimental measurement of the D1 magic wavelength in 40K at 1227.54(3) nm via tunable optical tweezer loss spectroscopy.
Atomic systems using 85Rb Rydberg atoms and vapor provide primary measurements of blackbody radiation temperature near 130 GHz and 24.5 THz with uncertainties of 1% and 0.13 K respectively.
Sidewall poled TFLN waveguides achieve 4.2 mW UV output at 390 nm with record efficiency and low propagation loss.
A piezoelectric-driven glass capillary launcher enables localized, high-efficiency (up to 93%) in-vacuum loading of silica spheres, nanodiamonds, and plate-like particles into single-beam, dual-beam, and standing-wave optical traps.
Shape resonances in Hg-Rb scattering states cause significant isotopic variations in collisional widths and shifts of the mercury clock transition.
