One-dimensional Lieb-Liniger Bose gas as nonrelativistic limit of the sinh-Gordon model

2010  PHYSICAL REVIEW A   81   043606  M. Kormos, G. Mussardo, and A. Trombettoni http://dx.doi.org/10.1103/PhysRevA.81.043606 Abstract: The repulsive Lieb-Liniger model can be obtained as the nonrelativistic limit of the sinh-Gordon model: all physical quantities of the latter model (S-matrix, … Continue reading

Non-Abelian Anyons from Degenerate Landau Levels of Ultracold Atoms in Artificial Gauge Potentials

2010  PHYSICAL REVIEW LETTERS   105   125304  M. Burrello and A. Trombettoni http://dx.doi.org/10.1103/PhysRevLett.105.125304 Abstract: We show that non-Abelian potentials acting on ultracold gases with two hyperfine levels can give rise to ground states with non-Abelian excitations. We consider a … Continue reading
