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…
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…
Robustness of topologically protected edge states in quantum walk experiments with neutral atoms
Thorsten Groh, Stefan Brakhane, Wolfgang Alt +3
Discrete-time quantum walks allow Floquet topological insulator materials to be explored using controllable systems such as ultracold atoms in optical lattices. By numerical simula…
