Kleinian singularities, derived categories and Hall algebras

M. Kapranov, E. Vasserot

We describe the derived category of coherent sheaves on the minimal resolution of the Kleinian singularity associated to a finite subgroup G of SL(2). Then, we give an application…

Heisenberg Spins on an Elastic Torus Section

Jerome Benoit, Rossen Dandoloff

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

Coarsening and persistence in a class of stochastic processes interpolating between the Ising and voter models

J-M Drouffe, C Godreche

We study the dynamics of a class of two dimensional stochastic processes, depending on two parameters, which may be interpreted as two different temperatures, respectively associat…

Kagom{é} Lattice Antiferromagnet Stripped to Its Basics

P. Azaria, C. Hooley, P. Lecheminant +2

We study a model of a spin S = 1/2 Heisenberg antiferromagnet on a one dimensional lattice with the local symmetry of the two dimensional kagom{é} lattice. Using three complementar…

Superconformal 6D (2,0) theories in superspace

C. Grojean, J. Mourad

A geometrical construction of superconformal transformations in six dimensional (2,0) superspace is proposed. Superconformal Killing vectors are determined. It is shown that the tr…

New Chiral Universality Class in a Frustrated Three-Leg Spin Ladder

P. Azaria, P. Lecheminant, A. A. Nersesyan

We study a model of three antiferromagnetic Heisenberg spin chains weakly coupled by on-rung and plaquette-diagonal interchain interactions. It is shown that the model exhi…

The Wilson Renormalization Group Approach of the Principal Chiral Model around Two Dimensions

B. Delamotte, D. Mouhanna, P. Lecheminant

We study the Principal Chiral Ginzburg-Landau-Wilson model around two dimensions within the Local Potential Approximation of an Exact Renormalization Group equation. This model, re…

Affine quantum groups and equivariant K-theory

Eric Vasserot

We give complete proofs of the K-theoretic construction of the quantized enveloping algebra of affine gl(n) sketched with V. Ginzburg in Internat. Math. Res. Notices, 3 (1993).

On the decomposition matrices of the quantized Schur algebra

Michela Varagnolo, Eric Vasserot

We prove the decomposition conjecture of Leclerc and Thibon for the Schur algebra. We also give a new approach to the Lusztig conjecture for the dimension of the simple U(sl_k)-mod…

First excitations of the spin 1/2 Heisenberg antiferromagnet on the kagomé lattice

Ch. Waldtmann, H. -U. Everts, B. Bernu +4

We study the exact low energy spectra of the spin 1/2 Heisenberg antiferromagnet on small samples of the kagomé lattice of up to N=36 sites. In agreement with the conclusions of pr…
