  • Parametric amplification of matter waves in dipolar spinor Bose-Einstein condensates 
    Deuretzbacher, Frank; Gebreyesus, Garu; Topic, Oliver; Scherer, Manuel; Lücke, Bernd; Ertmer, Wolfgang; Arlt, Jan J.; Klempt, Carsten; Santos, Luis (College Park, MD : American Physical Society, 2010)
    Spin-changing collisions may lead under proper conditions to the parametric amplification of matter waves in spinor Bose-Einstein condensates. Magnetic dipole-dipole interactions, although typically very weak in alkalimetal ...
  • Spontaneous breaking of spatial and spin symmetry in spinor condensates 
    Scherer, Manuel; Lücke, Bernd; Gebreyesus, Garu; Topic, Oliver; Deuretzbacher, Frank; Ertmer, Wolfgang; Santos, Luis; Arlt, Jan J.; Klempt, Carsten (College Park, MD : American Physical Society, 2010)
    Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric amplifier of spin modes, resulting in a ...
