  • 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 ...
  • Spontaneous Increase of Magnetic Flux and Chiral-Current Reversal in Bosonic Ladders: Swimming against the Tide 
    Greschner, Sebastian; Piraud, M.; Heidrich-Meisner, F.; McCulloch, I.P.; Schollwöck, U.; Vekua, T. (College Park, MD : American Physical Society, 2015)
    The interplay between spontaneous symmetry breaking in many-body systems, the wavelike nature of quantum particles and lattice effects produces an extraordinary behavior of the chiral current of bosonic particles in the ...
  • Spontaneous symmetry breaking in spinor Bose-Einstein condensates 
    Scherer, Manuel; Lücke, Bernd; Peise, Jan; Topic, Oliver; Gebreyesus, Garu; Deuretzbacher, Frank; Ertmer, Wolfgang; Santos, Luis; Klempt, Carsten; Arlt, Jan J. (College Park, MD : American Physical Society, 2013)
    We present an analytical model for the theoretical analysis of spin dynamics and spontaneous symmetry breaking in a spinor Bose-Einstein condensate (BEC). This allows for an excellent intuitive understanding of the processes ...
