Yangian symmetry in the Non Linear Schrodinger hierarchy
M. Mintchev, E. Ragoucy, P. Sorba +1
We study the Yangian symmetry of the multicomponent Quantum Nonlinear Schrodinger hierarchy in the framework of the Quantum Inverse Scattering Method. We give an explicit realizati…
Yangians, finite W-algebras and the Non Linear Schrodinger hierarchy
M. Mintchev, E. Ragoucy, P. Sorba +1
We show an algebra morphism between Yangians and some finite W-algebras. This correspondence is nicely illustrated in the framework of the Non Linear Schrodinger hierarchy. For suc…
Explicit solution of the quantum three-body Calogero-Sutherland model
A. M. Perelomov, E. Ragoucy, P. Zaugg
Quantum integrable systems generalizing Calogero-Sutherland systems were introduced by Olshanetsky and Perelomov (1977). Recently, it was proved that for systems with trigonometric…
Heterotic Coset Models and (0,2) String Vacua
Per Berglund, Clifford V. Johnson, Shamit Kachru +1
A Lagrangian definition of a large family of (0,2) supersymmetric conformal field theories may be made by an appropriate gauge invariant combination of a gauged Wess-Zumino-Witten…
The quantum Poincare group from quantum group contraction
Philippe Zaugg
We propose a contraction of the de Sitter quantum group leading to the quantum Poincare group in any dimensions. The method relies on the coaction of the de Sitter quantum group on…
Lattice Poincare as a quantum deformed algebra
Cesar Gomez, Henri Ruegg, Philippe Zaugg
We propose a definition of a Poincaré algebra for a two dimensional space--time with one discretized dimension. This algebra has the structure of a Hopf algebra. We use the link be…
