John T. Van Stan II,Jack Simmons atomic fundamental constants and for constraining their possible time variation. We present a brief overview of the results discussing in particular, the determination of the Rydberg constant, the relative atomic weight of the electron and proton, their mass ratio and the fine structure constant.

Lakes in Different Regions of Kazakhstan, molecular hydrogen (HD.) ions at 10 mK temperature. Achieving a resolution of 0.85 parts-per-billion (p.p.b.), we found the experimental value [.. = 383, 407, 177.38 (41) MHz] to be in agreement with the value from molecular theory [.. 383, 407, 177.150 (15) MHz] within 0.6 (1.1) p.p.b.

The Caspian Sea as a Stochastic Reservoirion current from sharp tips, with an interference visibility of 94%. With carrier-envelope phase-controlled laser pulses, we show furthermore how light-field sensitive currents can be excited in monolayer graphene via an interplay of interband and intraband electron dynamics including multiple Landau–Zener transitions.

Sergio M. Vicente-Serrano,Ricardo M. Trigofind a transition frequency of 2829833101679(103) kHz. The fractional accuracy of . . is 34 times better than previous measurements, and also the isotope shifts are measured with improved accuracy. This demonstration shows the potential of Ramsey-comb excitation for precision spectroscopy at short wavelengths.
