The clock is the latest demonstration that a much more precise definition of the official second is possible and that new applications of clocks are feasible.
Microcombs – chip-scale devices that generate and measure frequencies of light with exquisite accuracy – have transformed timekeeping and boosted optical
Far-infrared (or terahertz/THz, ca. 25 to 300 micron wavelength) femtosecond pulsed laser and Fourier-transform infrared methods are employed to measure
PRIME (Platform for Realizing Integrated Molecule Experiments) aims to establish primary, quantum-based realizations for both the radiometric watt and kelvin
Climate science increasingly relies on satellite- and ground-based spectrometers for the top-down inventories of atmospheric greenhouse gases, most notably
Theoretical work relevant to the determination of values of the fundamental constants, tests of bound-state quantum electrodynamics (QED), and methods of
