Shaping Cold Atom Clouds with a Vortex Beam
Arianna Bertoluzza, Sonja Lorenz, Paul Hampp +5
We introduce a method for shaping a cold atom cloud using a vortex laser beam with a polarization singularity at its center, which creates a point of vanishing intensity. Exploitin…

Bandwidth enhanced current noise suppression with a SERF magnetometer
Tobias Menold, Arianna Bertoluzza, Patrick Hildebrand +4
This work investigates the behavior of a spin-exchange relaxation-free (SERF) magnetometer integrated into the feedback branch of a closed-loop control circuit, designed to activel…

Trapping potentials and quantum gates for microwave-dressed Rydberg atoms on an atom chip
Iason Tsiamis, Georgios Doultsinos, Andreas F. Tzortzakakis +5
Rydberg atoms in dc electric fields acquire static dipole moments. When the atoms are close to a surface producing an inhomogeneous electric field, such as by the adsorbates on an…
