Creep motion of a model frictional system
Baptiste Blanc, Luis A. Pugnaloni, Jean-Christophe Géminard
We report on the dynamics of a model frictional system submitted to minute external perturbations. The system consists of a chain of sliders connected through elastic springs that…
Statistical analysis of the mass-to-flux ratio in turbulent cores: effects of magnetic field reversals and dynamo amplification
Erik Bertram, Christoph Federrath, Robi Banerjee +1
We study the mass-to-flux ratio (M/Φ) of clumps and cores in simulations of supersonic, magnetohydrodynamical turbulence for different initial magnetic field strengths. We investig…
Experimental evidence of a triadic resonance of plane inertial waves in a rotating fluid
Guilhem Bordes, Frédéric Moisy, Thierry Dauxois +1
Plane inertial waves are generated using a wavemaker, made of oscillating stacked plates, in a rotating water tank. Using particle image velocimetry, we observe that, after a trans…
The Atlas3D Project -- XI. Dense molecular gas properties of CO-luminous early-type galaxies
Alison Crocker, Melanie Krips, Martin Bureau +24
Surveying eighteen 12CO-bright galaxies from the ATLAS3D early-type galaxy sample with the Institut de Radio Astronomie Millimétrique (IRAM) 30m telescope, we detect 13CO(1-0) and…
Models of Stars, Brown Dwarfs and Exoplanets
France Allard, Derek Homeier, Bernd Freytag
Within the next few years, GAIA and several instruments aiming at imag- ing extrasolar planets will see first light. In parallel, low mass planets are being searched around red dwa…
The Biequivalence of Locally Cartesian Closed Categories and Martin-Löf Type Theories
Pierre Clairambault, Peter Dybjer
Seely's paper "Locally cartesian closed categories and type theory" contains a well-known result in categorical type theory: that the category of locally cartesian closed categorie…
An icy Kuiper-Belt around the young solar-type star HD 181327
J. Lebreton, J. -C. Augereau, W. -F. Thi +18
HD 181327 is a young F5/F6V star belonging to the Beta Pictoris moving group (12 Myr). It harbors an optically thin belt of circumstellar material at 90 AU. We aim to study the dus…
Two dimensional Dirac fermions in the presence of long-range correlated disorder
Andrei A. Fedorenko, David Carpentier, Edmond Orignac
We consider 2D Dirac fermions in the presence of three types of disorder: random scalar potential, random gauge potential and random mass with long-range correlations decaying as a…
Yellow supergiants as supernova progenitors: an indication of strong mass loss for red supergiants?
Cyril Georgy
The increasing observed number of supernova events allows for finding ever more frequently the progenitor star in archive images. In a few cases, the progenitor star is a yellow su…
Light scattering in inhomogeneous Tomonaga-Luttinger liquids
E. Orignac, R. Citro, S. De Palo +1
We derive the dynamical structure factor for an inhomogeneous Tomonaga-Luttinger liquid as can be formed in a confined strongly interacting one-dimensional gas. In view of current…
Phase transitions of quasistationary states in the Hamiltonian Mean Field model
Pierre de Buyl, Duccio Fanelli, Stefano Ruffo
The out-of-equilibrium dynamics of the Hamiltonian Mean Field (HMF) model is studied in presence of an externally imposed magnetic field h. Lynden-Bell's theory of violent relaxati…
Weak localization with nonlinear bosonic matter waves
Timo Hartmann, Josef Michl, Cyril Petitjean +4
We investigate the coherent propagation of dilute atomic Bose-Einstein condensates through irregularly shaped billiard geometries that are attached to uniform incoming and outgoing…
Backreaction in late-time cosmology
Thomas Buchert, Syksy Rasanen
We review the effect of the formation of nonlinear structures on the expansion rate, spatial curvature and light propagation in the universe, focusing on the possibility that it co…
Fluctuations, linear response and heat flux of an aging system
Juan Ruben Gomez-Solano, Artyom Petrosyan, Sergio Ciliberto
We measure the fluctuations of the position of a Brownian particle confined by an optical trap in an aging gelatin droplet after a fast quench. Its linear response to an external p…
Constraints on the MSSM from the Higgs Sector - A pMSSM Study of Higgs Searches, Bs -> mu+ mu- and Dark Matter Direct Detection
A. Arbey, M. Battaglia, F. Mahmoudi
We discuss the constraints on Supersymmetry in the Higgs sector arising from LHC searches, rare B decays and dark matter direct detection experiments. We show that constraints deri…
Renormalization flow for extreme value statistics of random variables raised to a varying power
Florian Angeletti, Eric Bertin, Patrice Abry
Using a renormalization approach, we study the asymptotic limit distribution of the maximum value in a set of independent and identically distributed random variables raised to a p…
Regular simplices and periodic billiard orbits
Nicolas Bedaride, Michael Rao
A simplex is the convex hull of points in which form an affine basis. A regular simplex is a simplex with sides of the same length. We consider the bil…
Wave Equation Numerical Resolution: a Comprehensive Mechanized Proof of a C Program
Sylvie Boldo, Francois Clement, Jean-Christophe Filliâtre +3
We formally prove correct a C program that implements a numerical scheme for the resolution of the one-dimensional acoustic wave equation. Such an implementation introduces errors…
Linear response theory for long-range interacting systems in quasistationary states
Aurelio Patelli, Shamik Gupta, Cesare Nardini +1
Long-range interacting systems, while relaxing to equilibrium, often get trapped in long-lived quasistationary states which have lifetimes that diverge with the system size. In thi…
A phenomenological theory of Eulerian and Lagrangian velocity fluctuations in turbulent flows
Laurent Chevillard, Bernard Castaing, Alain Arneodo +3
A phenomenological theory of the fluctuations of velocity occurring in a fully developed homogeneous and isotropic turbulent flow is presented. The focus is made on the fluctuation…
On-off intermittency over an extended range of control parameter
Eric Bertin
We propose a simple phenomenological model exhibiting on-off intermittency over an extended range of control parameter. We find that the distribution of the 'off' periods has as a…
