1/4 PBGS and Superparticle Actions
F. Delduc, E. Ivanov, S. Krivonos
We construct the worldline superfield massive superparticle actions which preserve 1/4 portion of the underlying higher-dimensional supersymmetry. We consider the cases of N=4/N=1…
1/4 Partial Breaking of Global Supersymmetry and New Superparticle Actions
F. Delduc, E. Ivanov, S. Krivonos
We construct the worldline superfield massive superparticle actions which preserve 1/4 portion of the underlying higher-dimensional supersymmetry. The rest of supersymmetry is spon…
Kinetic glass transition
Mauro Sellitto
Kinetic lattice-gas models display fragile glass behavior, in spite of their trivial Gibbs-Boltzmann measure. This suggests that the nature of glass transition might be, at least i…
Universal Fluctuations in Correlated Systems
S. T. Bramwell, K. Christensen, J. -Y. Fortin +7
The probability density function (PDF) of a global measure in a large class of highly correlated systems has been suggested to be of the same functional form. Here, we identify the…
Probing a regular orbit with spectral dynamics
Y. Copin, H. S. Zhao, P. T. de Zeeuw
We have extended the spectral dynamics formalism introduced by Binney & Spergel, and have implemented a semi-analytic method to represent regular orbits in any potential, making fu…
Non-Linear Poisson-Boltzmann Theory of a Wigner-Seitz Model for Swollen Clays
R. J. F. Leote de Carvalho, E. Trizac, J. -P. Hansen
Swollen stacks of finite-size disc-like Laponite clay platelets are investigated within a Wigner-Seitz cell model. Each cell is a cylinder containing a coaxial platelet at its cent…
Influence of Wetting Properties on Diffusion in a Confined Fluid
Yannick Alméras, Jean-Louis Barrat, Lydéric Bocquet
We briefly discuss how the wetting properties of a fluid/solid interface can indirectly influence the diffusion properties of fluid confined between two solid walls. This influence…
Structures de contact sur les varietes fibrees en cercles au-dessus d'une surface
Emmanuel Giroux
In this paper, we study the global behaviour of contact structures on oriented manifolds V which are circle bundles over a closed orientable surface S of genus g>0. We establish in…
A note on real forms of the complex N=4 supersymmetric Toda chain hierarchy in real N=2 and N=4 superspaces
F. Delduc, A. Sorin
Three inequivalent real forms of the complex N=4 supersymmetric Toda chain hierarchy (Nucl. Phys. B558 (1999) 545, solv-int/9907004) in the real N=2 superspace with one even and tw…
Chaotic dynamics and superdiffusion in a Hamiltonian system with many degrees of freedom
V. Latora, A. Rapisarda, S. Ruffo
We discuss recent results obtained for the Hamiltonian Mean Field model. The model describes a system of N fully-coupled particles in one dimension and shows a second-order phase t…
On the quantum inverse scattering problem
J. M. Maillet, V. Terras
A general method for solving the so-called quantum inverse scattering problem (namely the reconstruction of local quantum (field) operators in term of the quantum monodromy matrix…
Theoretical study of collective modes in DNA at ambient temperature
Simona Cocco, Remi Monasson
The instantaneous normal modes corresponding to base pair vibrations (radial modes) and twist angle fluctuations (angular modes) of a DNA molecule model at ambient temperature are…
Conformal invariance of domino tiling
Richard Kenyon
Let U be a multiply-connected region in R^2 with smooth boundary. Let P_epsilon be a polyomino in epsilon Z^2 approximating U as epsilon tends to 0. We show that, for certain bound…
Two-time scales, two-temperature scenario for nonlinear rheology
Ludovic Berthier, Jean-Louis Barrat, Jorge Kurchan
We investigate a general scenario for ``glassy'' or ``jammed'' systems driven by an external, non-conservative force, analogous to a shear force in a fluid. In this scenario, the d…
Quantum Backlund transformation for the integrable DST model
V. B. Kuznetsov, M. Salerno, E. K. Sklyanin
For the integrable case of the discrete self-trapping (DST) model we construct a Backlund transformation. The dual Lax matrix and the corresponding dual Backlund transformation are…
Mechanisms for slow strengthening in granular materials
W. Losert, J. -C. Geminard, S. Nasuno +1
Several mechanisms cause a granular material to strengthen over time at low applied stress. The strength is determined from the maximum frictional force F_max experienced by a shea…
Atomic structure and vibrational properties of icosahedral BC boron carbide
R. Lazzari, N. Vast, J. M. Besson +2
The atomic structure of icosahedral BC boron carbide is determined by comparing existing infra-red absorption and Raman diffusion measurements with the predictions of accurate…
Modeling Pressure-Ionization of Hydrogen in the Context of Astrophysics
D. Saumon, G. Chabrier, D. J. Wagner +1
The recent development of techniques for laser-driven shock compression of hydrogen has opened the door to the experimental determination of its behavior under conditions character…
Magnons in real materials from density-functional theory
Ralph Gebauer, Stefano Baroni
We present an implementation of the adiabatic spin-wave dynamics of Niu and Kleinman. This technique allows to decouple the spin and charge excitations of a many-electron system us…
Structures de contact en dimension trois et bifurcations des feuilletages de surfaces
Emmanuel Giroux
The main purpose of this article is to classify contact structures on some 3-manifolds, namely lens spaces, most torus bundles over a circle, the solid torus, and the thickened tor…
A Stochastic Description for Extremal Dynamics
S. Krishnamurthy, A. Tanguy, P. Abry +1
We show that extremal dynamics is very well modelled by the "Linear Fractional Stable Motion" (LFSM), a stochastic process entirely defined by two exponents that take into account…
Humidity Effects and Aging Behavior in Granular Media
F. Restagno, H. Gayvallet, L. Bocquet +1
We present a study of humidity effects on the maximum stability angle in granular media. We show that a granular medium of small glass beads exhibits aging properties : the first a…
Thermally Activated Dynamics of the Capillary Condensation
F. Restagno, L. Bocquet, T. Biben +1
This paper is devoted to the thermally activated dynamics of the capillary condensation. We present a simple model which enables us to identify the critical nucleus involved in the…
Atomic layering at the liquid silicon surface: a first- principles simulation
G. Fabricius, E. Artacho, D. Sanchez-Portal +3
We simulate the liquid silicon surface with first-principles molecular dynamics in a slab geometry. We find that the atom-density profile presents a pronounced layering, similar to…
