Spectral imaging of topological edge states in plasmonic waveguide arrays
Felix Bleckmann, Zlata Cherpakova, Stefan Linden +1
We report on the observation of a topologically protected edge state at the interface between two topologically distinct domains of the Su-Schrieffer-Heeger model, which we impleme…
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…
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…
