chiral WZNW model in superspace
F. Delduc, M. Magro
We study the Poisson bracket algebra of the supersymmetric chiral WZNW model in superspace. It involves two classical r-matrices, one of which comes from the geometrical cons…
Gauge invariant formulation of Toda and KdV systems in extended superspace
F. Delduc, M. Magro
We give a gauge invariant formulation of supersymmetric abelian Toda field equations in \n2 superspace. Superconformal invariance is studied. The conserved currents are shown…
On Discrete 3-Dimensional Equations Associated with the Local Yang-Baxter Relation
R. M. Kashaev
The local Yang-Baxter equation (YBE), introduced by Maillet and Nijhoff, is a proper generalization to 3 dimensions of the zero curvature relation. Recently, Korepanov has construc…
Strings from Gauged Wess-Zumino-Witten Models
E. Ragoucy, A. Sevrin, P. Sorba
We present an algebraic approach to string theory. An embedding of in a super Lie algebra together with a grading on the Lie algebra determines a nilpotent subalgebra of…
Monte Carlo Simulations of Conformal Theory Predictions for the 3-state Potts and Ising Models
Gerard Barkema, John McCabe
The critical properties of the 2D Ising and 3-state Potts models are investigated using Monte Carlo simulations. Special interest is given to measurement of 3-point correlation fun…
Stability of periodic arrays of vortices
Thierry Dauxois, Stephan Fauve, Laurette Tuckerman
The stability of periodic arrays of Mallier-Maslowe or Kelvin-Stuart vortices is discussed. We derive with the energy-Casimir stability method the nonlinear stability of this solut…
Linearization of W algebras and W superalgebras
J. O. Madsen, E. Ragoucy
In a recent paper, the authors have shown that the secondary reduction of W-algebras provides a natural framework for the linearization of W-algebras. In particular, it allows in a…
Generalized scaling in fully developed turbulence
R. Benzi, L. Biferale, S. Ciliberto +2
In this paper we report numerical and experimental results on the scaling properties of the velocity turbulent fields in several flows. The limits of a new form of scaling, named E…
N=4 super KdV hierarchy in N=4 and N=2 superspaces
F. Delduc, E. Ivanov, S. Krivonos
We present the results of further analysis of the integrability properties of the supersymmetric KdV equation deduced earlier by two of us (F.D. \& E.I.) as a hamiltonian flo…
Grassmannian Topological Kazama-Suzuki Models and Cohomology
Matthias Blau, Faheem Hussain, George Thompson
We investigate in detail the topological gauged Wess-Zumino-Witten models describing topological Kazama-Suzuki models based on complex Grassmannians. We show that there is a topolo…
Non-Polynomial Realizations of W-Algebras
F. Barbarin, E. Ragoucy, P. Sorba
Relaxing first-class constraint conditions in the usual Drinfeld-Sokolov Hamiltonian reduction leads, after symmetry fixing, to realizations of W algebras expressed in terms of all…
A new scaling property of turbulent flows
R. Benzi, L. Biferale, S. Ciliberto +2
We discuss a possible theoretical interpretation of the self scaling property of turbulent flows (Extended Self Similarity). Our interpretation predicts that, even in cases when ES…
On the intermittent energy transfer at viscous scales in turbulent flows
R. Benzi, L. Biferale, S. Ciliberto +2
In this letter we present numerical and experimental results on the scaling properties of velocity turbulent fields in the range of scales where viscous effects are acting. A gener…
Slave-particle quantization and sum rules in the t-J model
J. C. Le Guillou, E. Ragoucy
In the framework of constrained systems, we give the classical Hamiltonian formulation of slave-particle models and their correct quantization. The electron-momentum distribution f…
Effective Breather Trapping Mechanism for DNA Transcription
Julian J. -L. Ting, Michel Peyrard
Collective coordinate and direct numerical integration methods are applied to the analysis of a one-dimensional DNA model. A modification of the coupling constant in an extended re…
Critical Correlation Functions of the 2-Dimensional, 3-State Potts Model
John McCabe, Tomasz Wydro
We exploit the identification between the critical theory of the 3-state Potts model and the D_5 conformal model. This allows us to determine all 3-point correlations involving the…
Affine Toda field theory as a 3-dimensional integrable system
R. M. Kashaev, N. Reshetikhin
The affine Toda field theory is studied as a 2+1-dimensional system. The third dimension appears as the discrete space dimension, corresponding to the simple roots in the aff…
The Construction of Self-Similar Tilings
Richard Kenyon
We give a construction of a self-similar tiling of the plane with any prescribed expansion coefficient $λ\in\C$ (satisfying the necessary algebraic condition of being a complex Per…
OFF-SHELL (4,4) SUPERSYMMETRIC SIGMA MODELS WITH TORSION AS GAUGE THEORIES IN HARMONIC SUPERSPACE
Evgenyi A. Ivanov
Starting from the action of twisted multiplets in the harmonic superspace with a double set of harmonic variables, we present its generalization which provides…
Precision Tests of CPT Symmetry and Quantum Mechanics in the Neutral Kaon System
J. Ellis, J. Lopez, N. Mavromatos +1
We present a systematic phenomenological analysis of the tests of CPT symmetry that are possible within an {\em open} quantum-mechanical description of the neutral kaon system that…
Influence of the electric field on edge dislocations in smectics
R. Holyst, P. Oswald
The electric field applied perpendicularly to smectic layers breaks the rotational symmetry of the system. Consequently, the elastic energy associated with distortions induced by a…
Correlations in two-component log-gas systems
A. Alastuey, P. J. Forrester
A systematic study of the properties of particle and charge correlation functions in the two-dimensional Coulomb gas confined to a one-dimensional domain is undertaken. Two version…
A Testbench for the Nested Dipole Hypothesis of Kosterlitz and Thouless
A. Alastuey, P. J. Forrester
We consider the two-dimensional one-component plasma without a background and confined to a half plane near a metal wall. The particles are also subjected to an external potential…
A Link Invariant from Quantum Dilogarithm
R. M. Kashaev
The link invariant, arising from the cyclic quantum dilogarithm via the particular -matrix construction, is proved to coincide with the invariant of triangulated links in …
