SUMMARY:Séminaire du LPTMS: Thomas Quella - LPTMS\, salle 201\, 2ème éta
 ge\, Bât 100\, Campus d'Orsay - 19 Mai 15 11:00
DESCRIPTION:Topological aspects of SU(N) magnetism and its cold atom realiz
 ation\nThomas Quella\, Universität Köln\nSU(N) spin systems exhibit a nu
 mber of novel topological quantum states\, including specifically a variet
 y of Haldane phases (in 1D) and abelian and non-abelian spin liquid phases
  (in 2D). In this talk we will review the classification of Haldane phases
  and their characterization in terms of fractionalized boundary spins and 
 non-local string order parameters. Moreover\, we will address the possible
  realization of these phases in ultra-cold gases of alkaline-earth fermion
 s. If time permits we will also briefly comment on the systematic design o
 f critical and topological long-range SU(N) spin models in one and two dim
 ensions which are based on infinite dimensional matrix product states asso
 ciated with SU(N) WZW models.
