Collimation of dense atomic beams by Swept Velocity Shelving
Francesca FamÃ, Benedikt Heizenreder, Ananya Sitaram +4
Engineering continuous, high-flux, and collimated atomic beams is a useful resource for metrology and material deposition. Developments in this area have been essential for the evo…
Continuous cloud position spectroscopy using a magneto-optical trap
Benedikt Heizenreder, Ananya Sitaram, Sana Boughdachi +4
We demonstrate a continuous spectroscopy technique with frequency sensitivity well below the natural transition linewidth, while maintaining a locking range hundreds of times large…
Quasi-continuous sub-K strontium source without a high-finesse cavity stabilized laser
Sana Boughdachi, Benedikt Heizenreder, Ananya Sitaram +8
We demonstrate a quasi-continuous sub-K strontium source achieved without the use of a high-finesse cavity-locked laser. Our frequency reference is based on a dispersion-optimi…
Engineering Zeeman-manifold quintets using state-dependent light shifts in neutral atoms
Benedikt Heizenreder, Bas Gerritsen, Katya Fouka +4
We present a general method for engineering qudits through individually addressable transitions between Zeeman sublevels, achieved by combining a large linear Zeeman shift with a s…
Modeling of a continuous superradiant laser on the sub-mHz SP transition in neutral strontium-88
Swadheen Dubey, Georgy A. Kazakov, Benedikt Heizenreder +5
Continuous superradiance using a narrow optical transition has the potential to improve the short-term stability of state-of-the-art optical clocks. Even though pulsed superradiant…
