Matter-wave collimation to picokelvin energies with scattering length and potential shape control
Alexander Herbst, Timothé Estrampes, Henning Albers +7
The sensitivity of atom interferometers depends on their ability to realize long pulse separation times and prevent loss of contrast by limiting the expansion of the atomic ensembl…

Rapid generation of all-optical K Bose-Einstein condensates using a low-field Feshbach resonance
Alexander Herbst, Henning Albers, Knut Stolzenberg +2
Ultracold potassium is an interesting candidate for quantum technology applications and fundamental research as it allows controlling intra-atomic interactions via low-field magnet…

A high-flux source system for matter-wave interferometry exploiting tunable interactions
Alexander Herbst, Timothé Estrampes, Henning Albers +7
Atom interferometers allow determining inertial effects to high accuracy. Quantum-projection noise as well as systematic effects impose demands on large atomic flux as well as ultr…
