  author={Alexander Herbst and Henning Albers and Knut Stolzenberg and Sebastian-James Bode and Dennis Schlippert},
Ultracold potassium is an interesting candidate for quantum technology applications and funda-mental research as it allows controlling intra-atomic interactions via low-field magnetic Feshbach resonances. However, the realization of high-flux sources of Bose-Einstein condensates remains challenging due to the necessity of optical trapping to use magnetic fields as free parameter. We investigate the production of all-optical 39 K Bose-Einstein condensates with different scattering lengths using a…

All-optical matter-wave lens using time-averaged potentials

The precision of matter-wave sensors benefits from interrogating large-particle-number atomic ensembles at high cycle rates. Quantum-degenerate gases with their low effective temperatures allow for

One second interrogation time in a 200 round-trip waveguide atom interferometer

We report a multiple-loop guided atom interferometer in which the atoms make 200 small-amplitude round-trips, instead of one large single orbit. The approach is enabled by using ultracold 39 K gas in
