Extended E8 Invariance of 11-Dimensional Supergravity
S. de Buyl, M. Henneaux, L. Paulot
The hyperbolic Kac-Moody algebra E10 has repeatedly been suggested to play a crucial role in the symmetry structure of M-theory. Recently, following the analysis of the asymptotic…
Mesa-type patterns in the one-dimensional Brusselator and their stability
Theodore Kolokolnikov, Thomas Erneux, Juncheng Wei
The Brusselator is a generic reaction-diffusion model for a tri-molecular chemical reaction. We consider the case when the input and output reactions are slow. In this limit, we sh…
Resonances and final state interactions in the reaction pp->pK^+Lambda
A. Sibirtsev, J. Haidenbauer, H. -W. Hammer +1
A study of the strangeness production reaction pp->pK^+Lambda for excess energies of epsilon \le 150 MeV, accessible at high-luminosity accelerator facilities like COSY, is present…
Physical interpretation of initial conditions for fractional differential equations with Riemann-Liouville fractional derivatives
Nicole Heymans, Igor Podlubny
On a series of examples from the field of viscoelasticity we demonstrate that it is possible to attribute physical meaning to initial conditions expressed in terms of Riemann-Liouv…
Three-body continuum states on a Lagrange mesh
P. Descouvemont, E. M. Tursunov, D. Baye
Three-body continuum states are investigated with the hyperspherical method on a Lagrange mesh. The -matrix theory is used to treat the asymptotic behaviour of scattering wave f…
Analysis of the He decay into the continuum within a three-body model
E. M. Tursunov, D. Baye, P. Descouvemont
The beta-decay process of the He halo nucleus into the alpha+d continuum is studied in a three-body model. The He nucleus is described as an alpha+n+n system in hyperspheri…
Fluctuation theorem for currents and Schnakenberg network theory
David Andrieux, Pierre Gaspard
A fluctuation theorem is proved for the macroscopic currents of a system in a nonequilibrium steady state, by using Schnakenberg network theory. The theorem can be applied, in part…
Chapman-Enskog expansion about nonequilibrium states: the sheared granular fluid
James F. Lutsko
The Chapman-Enskog method of solution of kinetic equations, such as the Boltzmann equation, is based on an expansion in gradients of the deviations fo the hydrodynamic fields from…
Pseudo-Hermitian versus Hermitian position-dependent-mass Hamiltonians in a perturbative framework
B. Bagchi, C. Quesne, R. Roychoudhury
We formulate a systematic algorithm for constructing a whole class of Hermitian position-dependent-mass Hamiltonians which, to lowest order of perturbation theory, allow a descript…
Symplectic connections
Pierre Bieliavsky, Michel Cahen, Simone Gutt +2
This article is an overview of the results obtained in recent years on symplectic connections. We present what is known about preferred connections (critical points of a variationa…
Multiparametric Quantum Algebras and the Cosmological Constant
Chethan Krishnan, Edoardo Di Napoli
With a view towards applications for de Sitter, we construct the multi-parametric -deformation of the $so(5,\IC)$ algebra using the Faddeev-Reshetikhin-Takhtadzhyan (FRT) formal…
Kac-Moody algebras in gravity and M-theories
Laurent Houart
The formulation of gravity and M-theories as very-extended Kac-Moody invariant theories is reviewed. Exact solutions describing intersecting extremal brane configurations smeared i…
Energy and number of collisions fluctuations in inelastic gases
R. Lambiotte, M. Ausloos, J. M. Salazar
We study by numerical simulations the two-dimensional Inelastic Maxwell Model (IMM), and show how the inelasticity of collisions together with the fluctuations of the number of col…
Granular Matter: a wonderful world of clusters in far-from-equilibrium systems
M. Ausloos, R. Lambiotte, K. Trojan +2
In this paper, we recall various features of non equilibrium granular systems. Clusters with specific properties are found depending on the packing density, going from loose (a gra…
Overdamping by weakly coupled environments
Massimiliano Esposito, Fritz Haake
A quantum system weakly interacting with a fast environment usually undergoes a relaxation with complex frequencies whose imaginary parts are damping rates quadratic in the couplin…
Cosmological Constant and Noncommutative Spacetime
Xavier Calmet
We show that the cosmological constant appears as a Lagrange multiplier if nature is described by a canonical noncommutative spacetime. It is thus an arbitrary parameter unrelated…
On high energy tails in inelastic gases
R. Lambiotte, L. Brenig, J. M. Salazar
We study the formation of high energy tails in a one-dimensional kinetic model for granular gases, the so-called Inelastic Maxwell Model. We introduce a time- discretized version o…
Structure of 12Be: intruder d-wave strength at N=8
S. D. Pain, W. N. Catford, N. A. Orr +21
The breaking of the N=8 shell-model magic number in the 12Be ground state has been determined to include significant occupancy of the intruder d-wave orbital. This is in marked con…
Control of mixed-state quantum systems by a train of short pulses
D. Sugny, A. Keller, O. Atabek +4
A density matrix approach is developped for the control of a mixed-state quantum system using a time-dependent external field such as a train of pulses. This leads to the definitio…
Hydrodynamics of an inelastic gas with implications for sonochemistry
James F. Lutsko
The hydrodynamics for a gas of hard-spheres which sometimes experience inelastic collisions resulting in the loss of a fixed, velocity-independent, amount of energy is investig…
Laser control for the optimal evolution of pure quantum states
D. Sugny, A. Keller, O. Atabek +4
Starting from an initial pure quantum state, we present a strategy for reaching a target state corresponding to the extremum (maximum or minimum) of a given observable. We show tha…
Theoretical evidence for a dense fluid precursor to crystallization
James F. Lutsko, Grégoire Nicolis
We present classical density functional theory calculations of the free energy landscape for fluids below their triple point as a function of density and crystallinity. We find tha…
Brieskorn manifolds as contact branched covers of spheres
Ferit Ozturk, Klaus Niederkrüger
We show that Brieskorn manifolds with their standard contact structures are contact branched coverings of spheres. This covering maps a contact open book decomposition of the Bries…
Relation between widths of proton resonances and neutron asymptotic normalization coefficients in mirror states of light nuclei in a microscopic cluster model
N. K. Timofeyuk, P. Descouvemont
It has been suggested recently ({\it Phys. Rev. Lett.} 91, 232501 (2003)) that the widths of narrow proton resonances are related to neutron Asymptotic Normalization Coefficients (…
