Roche lobe effects on the atmospheric loss of "Hot Jupiters"
N. V. Erkaev, H. Lammer, Yu. N. Kulikov +4
Observational evidence of a hydrodynamically evaporating upper atmosphere of HD209458b (Vidal-Madjar et al. 2003; 2004) and recent theoretical studies on evaporation scenarios of `…
Bubbles and denaturation in DNA
Titus S. van Erp, Santiago Cuesta-Lopez, Michel Peyrard
The local opening of DNA is an intriguing phenomenon from a statistical physics point of view, but is also essential for its biological function. For instance, the transcription an…
Non-Clairvoyant Batch Sets Scheduling: Fairness is Fair enough
Julien Robert, Nicolas Schabanel
Scheduling questions arise naturally in many different areas among which operating system design, compiling,... In real life systems, the characteristics of the jobs (such as relea…
Some comments on the universal constant in DSR
Florian Girelli, Etera R. Livine
Deformed Special Relativity is usually presented as a deformation of Special Relativity accommodating a new universal constant, the Planck mass, while respecting the relativity pri…
Correlation lengths for random polymer models and for some renewal sequences
F. L. Toninelli
We consider models of directed polymers interacting with a one-dimensional defect line on which random charges are placed. More abstractly, one starts from renewal sequence on …
Revisiting Matrix Product on Master-Worker Platforms
Jack Dongarra, Jean-Francois Pineau, Yves Robert +2
This paper is aimed at designing efficient parallel matrix-product algorithms for heterogeneous master-worker platforms. While matrix-product is well-understood for homogeneous 2D-…
A quasi-elastic regime for vibrated granular gases
Sébastien Aumaître, Angel Alastuey, Stephan Fauve
Using simple scaling arguments and two-dimensional numerical simulations of a granular gas excited by vibrating one of the container boundaries, we study a double limit of small $1…
Observation of intermittency in wave turbulence
Eric Falcon, Stéphan Fauve, Claude Laroche
We report the observation of intermittency in gravity-capillary wave turbulence on the surface of mercury. We measure the temporal fluctuations of surface wave amplitude at a given…
Single beam interferometric angle measurement
Pierdomenico Paolino, Ludovic Bellon
We present an application of a quadrature phase interferometer to the measurement of the angular position of a parallel laser beam with interferometric precision. In our experiment…
Non-commutative Weitzenboeck geometry, gerbe modules, and WZW branes
Andreas Recknagel, Rafal R. Suszek
We study the non-commutative matrix model which arises as the low-energy effective action of open strings in WZW models. We re-derive this fuzzy effective gauge dynamics in two dif…
Tidal dissipation within hot Jupiters: a new appraisal
Benjamin Levrard, Alexandre Morgado Correia, Gilles Chabrier +3
Eccentricity or obliquity tides have been proposed as the missing energy source that may explain the anomalously large radius of some transiting ``hot Jupiters''. To maintain a non…
LeMoMaF: Lensed Mock Map Facility
Jaime E. Forero-Romero, Jeremy Blaizot, Julien Devriendt +2
We present the Lensed Mock Map Facility (LeMoMaF), a tool designed to perform mock weak lensing measurements on numerically simulated chunks of the universe. Coupling N-body simula…
Young Nuclei in Dwarf Elliptical Galaxies
Igor Chilingarian, Olga Sil'chenko, Victor Afanasiev +1
We report discovery of young embedded structures in three diffuse elliptical galaxies (dE) in the Virgo cluster: IC 783, IC 3468, and IC 3509. We performed 3D spectroscopic observa…
Evidence of Luttinger liquid behavior in one-dimensional dipolar quantum gases
R. Citro, E. Orignac, S. De Palo +1
The ground state and structure of a one-dimensional Bose gas with dipolar repulsions is investigated at zero temperature by a combined Reptation Quantum Monte Carlo (RQMC) and boso…
Quantum causal histories in the light of quantum information
Etera R. Livine, Daniel R. Terno
We use techniques of quantum information theory to analyze the quantum causal histories approach to quantum gravity. We show that while it is consistent to introduce closed timelik…
Gauging N=4 supersymmetric mechanics II: (1,4,3) models from the (4,4,0) ones
F. Delduc, E. Ivanov
Exploiting the gauging procedure developed by us in hep-th/0605211, we study the relationships between the models of N=4 mechanics based on the off-shell multiplets (4,4,0) and (1,…
Interstellar medium disruption in the Centaurus A group
A. Bouchard, H. Jerjen, G. S. Da Costa +1
We present the results of a 21 cm neutral hydrogen (HI) line detection experiment in the direction of 18 low luminosity dwarf galaxies of the Centaurus A group, using the Australia…
Spheroid ages, kinematics and BH relations
Eric Emsellem
I very briefly discuss the ages and kinematics of spheroids as well as the black hole relations, via a few recent and illustrative studies, which include results on the downsizing,…
On correlation functions of integrable models associated to the six-vertex R-matrix
N. Kitanine, K. Kozlowski, J. M. Maillet +2
We derive an analog of the master equation obtained recently for correlation functions of the XXZ chain for a wide class of quantum integrable systems described by the R-matrix of…
Hidden Quantum Gravity in 4d Feynman diagrams: Emergence of spin foams
Aristide Baratin, Laurent Freidel
We show how Feynman amplitudes of standard QFT on flat and homogeneous space can naturally be recast as the evaluation of observables for a specific spin foam model, which provides…
Intensive thermodynamic parameters in nonequilibrium systems
Eric Bertin, Kirsten Martens, Olivier Dauchot +1
Considering a broad class of steady-state nonequilibrium systems for which some additive quantities are conserved by the dynamics, we introduce from a statistical approach intensiv…
Some aspects of electrical conduction in granular systems of various dimensions
Mathieu Creyssels, Stéphane Dorbolo, Alexandre Merlen +3
We report on measurements of the electrical conductivity in both a 2D triangular lattice of metallic beads and in a chain of beads. The voltage/current characteristics are qualitat…
Heat blanketing envelopes and thermal radiation of strongly magnetized neutron stars
A. Y. Potekhin, G. Chabrier, D. G. Yakovlev
Strong (B >> 10^9 G) and superstrong (B > 10^{14} G) magnetic fields profoundly affect many thermodynamic and kinetic characteristics of dense plasmas in neutron star envelopes. In…
