Robust and compact single-lens crossed-beam optical dipole trap for Bose-Einstein condensation in microgravity

Jan Simon Haase, Alexander Fieguth, Igor Bröckel +3

We present a novel concept for a compact and robust crossed-beam optical dipole trap (cODT) based on a single lens, designed for the efficient generation of Bose-Einstein condensat…

All-optical production of Bose-Einstein condensates with 2 Hz repetition rate

Mareike Hetzel, Martin Quensen, Jan Simon Haase +1

Bose-Einstein condensates (BECs) of neutral atoms constitute an important quantum system for fundamental research and precision metrology. Many applications require short preparati…

In-Situ Differential-Light-Shift Cancellation for Trapped-Atom Clocks

Jan Simon Haase, Alexander Fieguth, Igor Bröckel +2

Differential light shifts (DLS) induced by optical trapping fields fundamentally limit the stability and accuracy of trapped-atom microwave clocks. We demonstrate an in-situ method…

An entanglement-enhanced atomic gravimeter

Christophe Cassens, Bernd Meyer-Hoppe, Ernst Rasel +1

Interferometers based on ultra-cold atoms enable an absolute measurement of inertial forces with unprecedented precision. However, their resolution is fundamentally restricted by q…
