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…
Fast, high-precision optical polarization synthesizer for ultracold-atom experiments
Carsten Robens, Stefan Brakhane, Wolfgang Alt +3
We present a novel approach to precisely synthesize arbitrary polarization states of light with a high modulation bandwidth. Our approach consists of superimposing two laser light…
Atomic "bomb testing": the Elitzur-Vaidman experiment violates the Leggett-Garg inequality
Carsten Robens, Wolfgang Alt, Clive Emary +2
Elitzur and Vaidman have proposed a measurement scheme that, based on the quantum superposition principle, allows one to detect the presence of an object --- in a dramatic scenario…
Low-entropy states of neutral atoms in polarization-synthesized optical lattices
Carsten Robens, Jonathan Zopes, Wolfgang Alt +3
We create low-entropy states of neutral atoms by utilizing a conceptually new optical-lattice technique that relies on a high-precision, high-bandwidth synthesis of light polarizat…
