Paraxial Skyrmionic beams
Sijia Gao, Jörg B. Götte, Fiona C. Speirits +3
Vector vortex beams possess a topological property that derives both from the spatially varying amplitude of the field and also from its varying polarization. This property arises…

Superpositions of up to six plane waves without electric-field interference
K. C. van Kruining, R. P. Cameron, J. B. Götte
Superpositions of coherent light waves typically interfere. We present superpositions of up to six plane waves which defy this expectation by having a perfectly homogeneous mean sq…

Trapping atoms in the evanescent field of laser written wave guides
Dario Jukic, A Moqanaki, P Walther +3
We analyze evanescent fields of laser written waveguides and show that they can be used to trap atoms close to the surface of an integrated optical atom chip. In contrast to subwav…
