Measurement of the lowest millimetre-wave transition frequency of the CH radical
S. Truppe, R. J. Hendricks, E. A. Hinds +1
The CH radical offers a sensitive way to test the hypothesis that fundamental constants measured on earth may differ from those observed in other parts of the universe. The startin…
A search for varying fundamental constants using Hz-level frequency measurements of cold CH molecules
S. Truppe, R. J. Hendricks, S. K. Tokunaga +5
Many modern theories predict that the fundamental constants depend on time, position, or the local density of matter. We develop a spectroscopic method for pulsed beams of cold mol…
Characterization of a cryogenic beam source for atoms and molecules
N. E. Bulleid, S. M. Skoff, R. J. Hendricks +3
We present a combined experimental and theoretical study of beam formation from a cryogenic buffer gas cell. Atoms and molecules are loaded into the cell by laser ablation of a tar…
