VLT/NACO infrared adaptive optics images of small scale structures in OMC1
Francois Lacombe, Eric Gendron, Daniel Rouan +10
Near-infrared observations of line emission from excited H2 and in the continuum are reported in the direction of the Orion molecular cloud OMC1, using the European Southern Observ…
Freezing of Triangulations
J-P. Kownacki
Zero temperature dynamics of two dimensional triangulations of a torus with curvature energy is described. Numerical simulations strongly suggest that the model get frozen in metas…
Dynamical Symmetry Enlargement Versus Spin-Charge Decoupling in the One-Dimensional SU(4) Hubbard Model
R. Assaraf, P. Azaria, E. Boulat +2
We investigate dynamical symmetry enlargement in the half-filled SU(4) Hubbard chain using non-perturbative renormalization group and Quantum Monte Carlo techniques. A spectral gap…
Z_3 Quantum Criticality in a spin-1/2 chain model
P. Lecheminant, E. Orignac
The stability of the magnetization plateau phase of the XXZ spin-1/2 Heisenberg chain with competing interactions is investigated upon switching on a staggered transverse m…
Kink propagation in a two-dimensional curved Josephson junction
C. Gorria, Yu. B. Gaididei, M. P. Soerensen +2
We consider the propagation of sine-Gordon kinks in a planar curved strip as a model of nonlinear wave propagation in curved wave guides. The homogeneous Neumann transverse boundar…
Homotopy and duality in non-Abelian lattice gauge theory
Romain Attal
We propose an approach of lattice gauge theory based on a homotopic interpretation of its degrees of freedom. The basic idea is to dress the plaquettes of the lattice to view them…
From spaces of polygons to spaces of polyhedra following Bavard, Ghys and Thurston
Francois Fillastre
After work of W. P. Thurston, C. Bavard and É. Ghys constructed particular hyperbolic polyhedra from spaces of deformations of Euclidean polygons. We present this construction as a…
Construction of dynamical quadratic algebras
Zoltan Nagy, Jean Avan, Genevieve Rollet
We propose a dynamical extension of the quantum quadratic exchange algebras introduced by Freidel and Maillet. It admits two distinct fusion structures. A simple example is provide…
Classification of reflection matrices related to (super) Yangians and application to open spin chain models
D. Arnaudon, J. Avan, N. Crampe' +3
We present a classification of diagonal, antidiagonal and mixed reflection matrices related to Yangian and super-Yangian R matrices associated to the infinite series so(m), sp(n) a…
Study of the influence of surface anisotropy and lattice structure on the behaviour of a small magnetic cluster
Laura Hernández, Claire Pinettes
We have studied by Monte Carlo simulations the thermal behaviour of a small (N=13 particles) cluster described by a Heisenberg model, including nearest-neighbour ferromagnetic inte…
Star-triangle equivalence in soap froths
M. Mancini, Ch. Oguey
In two dimensional foams at equilibrium, triangular bubbles can be freely exchanged with 3-fold stars --three edges ending at a central vertex. This theorem is deduced here from Mo…
Dislocation lines as the precursor of the melting of crystalline solids observed in Monte Carlo simulations
L. Gómez, A. Dobry, Ch. Geuting +2
The microscopic mechanism of the melting of a crystal is analyzed by the constant pressure Monte Carlo simulation of a Lennard-Jones fcc system. Beyond a temperature of the order o…
Contact boundaries of hypersurface singularities and of complex polynomials
C. Caubel, M. Tibar
We survey some recent results concerning the behaviour of the contact structure defined on the boundary of a complex isolated hypersurface singularity or on the boundary at infinit…
