  • Coherent evolution of bouncing bose-einstein condensates 
    Bongs, Kai; Burger, S.; Birkl, G.; Sengstock, K.; Ertmer, Wolfgang; Rzazewski, K.; Sanpera, A.; Lewenstein, M. (American Physical Society, 1999)
    We investigate the evolution of Bose-Einstein condensates falling under gravity and bouncing off a mirror formed by a far-detuned sheet of light. After reflection, the atomic density profile develops splitting and interference ...
  • Dark solitons in bose-einstein condensates 
    Burger, S.; Bongs, Kai; Dettmer, S.; Ertmer, Wolfgang; Sengstock, K.; Sanpera, A.; Shlyapnikov, G.V.; Lewenstein, M. (American Physical Society, 1999)
    Dark solitons in cigar-shaped Bose-Einstein condensates of 87Rb are created by a phase imprinting method. Coherent and dissipative dynamics of the solitons has been observed. © 1999 The American Physical Society.
  • Optical generation of vortices in trapped Bose-Einstein condensates 
    Dobrek, Ł.; Gajda, M.; Lewenstein, M.; Sengstock, K.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 1999)
    We demonstrate numerically the efficient generation of vortices in Bose-Einstein condensates (BECs) by using a “phase imprinting” method. The method consists of passing a far-off-resonant laser pulse through an absorption ...
