Direct measurement of the Wigner function of atoms in an optical trap
Falk-Richard G. Winkelmann, Carrie A. Weidner, Gautam Ramola +3
We present a scheme that uses Ramsey interferometry to directly probe the Wigner function of a neutral atom confined in an optical trap. The proposed scheme relies on the well-esta…
Ramsey imaging of optical traps
Gautam Ramola, Richard Winkelmann, Karthik Chandrashekara +4
Mapping the potential landscape with high spatial resolution is crucial for quantum technologies based on ultracold atoms. Yet, imaging optical dipole traps is challenging because…
A high numerical aperture (NA = 0.92) objective lens for imaging and addressing of cold atoms
Carsten Robens, Stefan Brakhane, Wolfgang Alt +5
We have designed, built, and characterized a high-resolution objective lens that is compatible with an ultra-high vacuum environment. The lens system exploits the principle of the…
