We report the 2018 self-consistent values of constants and conversion factors of physics and
chemistry recommended by the Committee on Data of the International Science Council …

We report a precise measurement of the parity-violating (PV) asymmetry A PV in the elastic
scattering of longitudinally polarized electrons from Ca 48. We measure A PV= 2668±106 …

Einstein's theory of general relativity states that clocks at different gravitational potentials tick
at different rates relative to lab coordinates—an effect known as the gravitational redshift. As …

BACKGROUND The generation and control of coherent electromagnetic waves, such as
those provided by electronic oscillators in the radio frequency domain or lasers in the optical …

Atomic clocks are vital in a wide array of technologies and experiments, including tests of
fundamental physics. Clocks operating at optical frequencies have now demonstrated …

Laser cooling and trap**,, and magneto-optical trap** methods in particular, have
enabled groundbreaking advances in science, including Bose–Einstein condensation …

Optical frequency combs were developed nearly two decades ago to support the world's
most precise atomic clocks. Acting as precision optical synthesizers, frequency combs …
