Chirally Stabilized Critical State in Marginally Coupled Spin and Doped Systems

P. Azaria, P. Lecheminant

We study a class of one-dimensional models consisting of a frustrated (N+1)-leg spin ladder, its asymmetric doped version as a special example of a Luttinger liquid in an active en…

Conditions on the Occurrence of Magnetic Moments in Quasicrystals and Related Phases

Guy Trambly de Laissardiere, Didier Mayou

We analyze the criterion for the appearance of magnetic moments in quasicrystals approximants and liquids Al-Mn. In a Hartree-Fock scheme, it is shown that the Stoner criterion (Un…

Effect of symmetry breaking perturbations in the one-dimensional SU(4) spin-orbital model

Patrick Azaria, Edouard Boulat, Philippe Lecheminant

We study the effect of symmetry breaking perturbations in the one-dimensional SU(4) spin-orbital model. We allow the exchange in spin () and orbital () channel to be diff…

Heisenberg Spins on a Cylinder Section

Jerome Benoit, Rossen Dandoloff, Avadh Saxena

Classical Heisenberg spins in the continuum limit (i.e. the nonlinear sigma-model) are studied on an elastic cylinder section with homogeneous boundary conditions. The latter may s…

Super Fivebranes near the boundary of

C. Grojean, J. Mourad

We determine, to the first order in the radius of Anti-de-Sitter, the realisation of the superconformal algebra on vector fields. We then calculate, to this order, the…

Metal-insulator transition in the one-dimensional SU(N) Hubbard model

Roland Assaraf, Patrick Azaria, Michel Caffarel +1

We investigate the metal-insulator transition of the one-dimensional SU(N) Hubbard model for repulsive interaction. Using the bosonization approach a Mott transition in the charge…
