Systematic-free limit on new light scalar bosons via isotope shift spectroscopy in Ca
Timothy T. Chang, Bless Bah Awazi, Julian C. Berengut +2
We report a precise measurement of the isotope shifts in the SD electric quadrupole transition at 732~nm in Ca via high-r…
Part-per-billion measurement of the electric quadrupole transition isotope shifts between Ca and Ca
Felix W. Knollmann, Ashay N. Patel, S. Charles Doret
We report a precise measurement of the isotope shifts in the SD electric quadrupole transition at 729~nm in the Ca. The m…
Simple, low-noise piezo driver with feed-forward for broad tuning of external cavity diode lasers
S. Charles Doret
We present an inexpensive, low-noise (V, 0.1~Hz - 100~kHz) design for a piezo driver suitable for frequency tuning of external-cavity diode lasers. This simple driv…
Spatially uniform single-qubit gate operations with near-field microwaves and composite pulse compensation
Christopher M. Shappert, J. True Merrill, K. R. Brown +7
We present a microfabricated surface-electrode ion trap with a pair of integrated waveguides that generate a standing microwave field resonant with the 171Yb+ hyperfine qubit. The…
Large spin relaxation rates in trapped submerged-shell atoms
Colin B. Connolly, Yat Shan Au, S. Charles Doret +2
Spin relaxation due to atom-atom collisions is measured for magnetically trapped erbium and thulium atoms at a temperature near 500 mK. The rate constants for Er-Er and Tm-Tm colli…
Spin-exchange collisions of submerged shell atoms below 1 Kelvin
J. G. E. Harris, S. V. Nguyen, S. C. Doret +2
Angular momentum changing collisions can be suppressed in atoms whose valence electrons are submerged beneath filled shells of higher principle quantum number. To determine whether…
