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…
INTENTAS -- An entanglement-enhanced atomic sensor for microgravity
O. Anton, I. Bröckel, D. Derr +21
The INTENTAS project aims to develop an atomic sensor utilizing entangled Bose-Einstein condensates (BECs) in a microgravity environment. This key achievement is necessary to advan…
Optomechanical vector sensing of new forces at 6 micron separation
Gautam Venugopalan, Clarke A. Hardy, Kenneth Kohn +10
The search for new gravity-like interactions at the sub-millimeter scale is a compelling area of research, with important implications for the understanding of classical gravity an…
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…
