Fourier synthesis of optical potentials for atomic quantum gases
Gunnar Ritt, Carsten Geckeler, Tobias Salger +2
We demonstrate a scheme for the Fourier synthesis of periodic optical potentials with asymmetric unit cells for atoms. In a proof of principle experiment, an atomic Bose-Einstein c…
Interference of an array of atom lasers
Giovanni Cennini, Carsten Geckeler, Gunnar Ritt +1
We report on the observation of interference of a series of atom lasers. A comb-like array of coherent atomic beams is generated by outcoupling atoms from distinct Bose-Einstein co…
Interference of a variable number of coherent atomic sources
Giovanni Cennini, Carsten Geckeler, Gunnar Ritt +1
We have studied the interference of a variable number of independently created microcondensates in a CO-laser optical lattice. The observed average interference contr…
