  • Dynamics of Dark Solitons in Elongated Bose-Einstein Condensates 
    Muryshev, A.; Shlyapnikov, G.V.; Ertmer, Wolfgang; Sengstock, K.; Lewenstein, M. (American Physical Society, 2002)
    We find two types of moving dark soliton textures in elongated condensates: nonstationary kinks and proper dark solitons. The latter have a flat notch region and we obtain the diagram of their dynamical stability. At finite ...
  • Efficient magneto-optical trapping of a metastable helium gas 
    Pereira Dos Santos, F.; Perales, F.; Léonard, J.; Sinatra, A.; Wang, J.; Pavone, F.S.; Rasel, E.; Unnikrishnan, C.S.; Leduc, M. (Les Ulis : EDP Sciences, 2001)
    This article presents a new experiment aiming at BEC of metastable helium atoms. It describes the design of a high flux discharge source of atoms and a robust laser system using a DBR diode coupled with a high power Yb ...
  • Micro-optical Realization of Arrays of Selectively Addressable Dipole Traps: A Scalable Configuration for Quantum Computation with Atomic Qubits 
    Dumke, R.; Volk, M.; Müther, T.; Buchkremer, F.B.J.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2002)
    We experimentally demonstrate novel structures for the realization of registers of atomic qubits: We trap neutral atoms in one- and two-dimensional arrays of far-detuned dipole traps obtained by focusing a red-detuned laser ...
