Bloch oscillations of atoms in an optical multiphoton potential
Tobias Salger, Gunnar Ritt, Carsten Geckeler +2
We report on experiments studying transport properties of an atomic Bose-Einstein condensate in an optical lattice of spatial period , where is an integer, realized with…
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…
Bose-Einstein Condensation in a CO_2-laser Optical Dipole Trap
Giovanni Cennini, Gunnar Ritt, Carsten Geckeler +1
We report on the achieving of Bose-Einstein condensation of a dilute atomic gas based on trapping atoms in tightly confining CO_2-laser dipole potentials. Quantum degeneracy of rub…
All-Optical Realization of an Atom Laser
Giovanni Cennini, Gunnar Ritt, Carsten Geckeler +1
We demonstrate an atom laser using all-optical techniques. A Bose-Einstein condensate of rubidium atoms is created by direct evaporative cooling in a quasistatic dipole trap realiz…
