LQG propagator: III. The new vertex
Emanuele Alesci, Eugenio Bianchi, Carlo Rovelli
In the first article of this series, we pointed out a difficulty in the attempt to derive the low-energy behavior of the graviton two-point function, from the loop-quantum-gravity…
Large grains in disks around young stars: ATCA observations of WW Cha, RU Lup, and CS Cha
Dave Lommen, Sarah Maddison, Chris Wright +3
Grains in disks around young stars grow from interstellar submicron sizes to planetesimals over the course of several Myr. Thermal emission of large grains or pebbles can be best o…
Dark Energy vs. Dark Matter: Towards a Unifying Scalar Field?
A. Arbey
The standard model of cosmology suggests the existence of two components, "dark matter" and "dark energy", which determine the fate of the Universe. Their nature is still under inv…
Superfluidity and Anderson localisation for a weakly interacting Bose gas in a quasiperiodic potential
Xiaolong Deng, Roberta Citro, Anna Minguzzi +1
Using exact diagonalisation and Density Matrix Renormalisation group (DMRG) approach, we analyse the transition to a localised state of a weakly interacting quasi-1D Bose gas subje…
Far-from-equilibrium state in a weakly dissipative model
Eric Bertin, Olivier Dauchot
We address, on the example of a simple solvable model, the issue of whether the stationary state of dissipative systems converges to an equilibrium state in the low dissipation lim…
Cosmological constraints on unifying Dark Fluid models
A. Arbey
In the standard model of cosmology, dark matter and dark energy are presently the two main contributors to the total energy in the Universe. However, these two dark components are…
Experimental study of out of equilibrium fluctuations in a colloidal suspension of Laponite using optical traps
Pierre Jop, J. Ruben Gomez-Solano, Artyom Petrosyan +1
This work is devoted to the study of displacement fluctuations of micron-sized particles in an aging colloidal glass. We address the issue of the validity of the fluctuation dissip…
A Lagrangian approach to the Barrett-Crane spin foam model
Valentin Bonzom, Etera R. Livine
We provide the Barrett-Crane spin foam model for quantum gravity with a discrete action principle, consisting in the usual BF term with discretized simplicity constraints which in…
Structural results for free Araki-Woods factors and their continuous cores
Cyril Houdayer
We show that for any type free Araki-Woods factor associated with an orthogonal representation of on a separable real Hilbe…
Intersecting Attractors
S. Ferrara, A. Marrani, J. F. Morales +1
We apply the entropy formalism to the study of the near-horizon geometry of extremal black p-brane intersections in D>5 dimensional supergravities. The scalar flow towards the hori…
Acceleration statistics of finite-sized particles in turbulent flow: the role of Faxen forces
Enrico Calzavarini, Romain Volk, Mickael Bourgoin +3
The dynamics of particles in turbulence when the particle-size is larger than the dissipative scale of the carrier flow is studied. Recent experiments have highlighted signatures o…
High resolution dynamical mapping of social interactions with active RFID
Alain Barrat, Ciro Cattuto, Vittoria Colizza +3
In this paper we present an experimental framework to gather data on face-to-face social interactions between individuals, with a high spatial and temporal resolution. We use activ…
A probable giant planet imaged in the Beta Pictoris disk
A. -M. Lagrange, D. Gratadour, G. Chauvin +12
Since the discovery of its dusty disk in 1984, Beta Pictoris has become the prototype of young early-type planetary systems, and there are now various indications that a massive Jo…
Thermal noise of microcantilevers in viscous fluids
Ludovic Bellon
We present a simple theoretical framework to describe the thermal noise of a microscopic mechanical beam in a viscous fluid: we use the Sader approach to describe the effect of the…
Dynamical Evolution of AGN Host Galaxies - Gas In/Out-Flow Rates in 7 NUGA Galaxies
Sebastian Haan, Eva Schinnerer, Eric Emsellem +4
To examine the role of the host galaxy structure in fueling nuclear activity, we estimated gas flow rates from several kpc down to the inner few 10 pc for seven nearby spiral galax…
Testing bibliometric indicators by their prediction of scientists promotions
Pablo Jensen, Jean-Baptiste Rouquier, Yves Croissant
We have developed a method to obtain robust quantitative bibliometric indicators for several thousand scientists. This allows us to study the dependence of bibliometric indicators…
Spectral measure of heavy tailed band and covariance random matrices
Serban Belinschi, Amir Dembo, Alice Guionnet
We study the asymptotic behavior of the appropriately scaled and possibly perturbed spectral measure of large random real symmetric matrices with heavy tailed entries. Specific…
Matrix Models as Non-commutative Field Theories on R^3
Etera R. Livine
In the context of spin foam models for quantum gravity, group field theories are a useful tool allowing on the one hand a non-perturbative formulation of the partition function and…
Marginal relevance of disorder for pinning models
Giambattista Giacomin, Hubert Lacoin, Fabio Lucio Toninelli
The effect of disorder on pinning and wetting models has attracted much attention in theoretical physics. In particular, it has been predicted on the basis of the Harris criterion…
Scientists who engage with society perform better academically
Pablo Jensen, Jean-Baptiste Rouquier, Pablo Kreimer +1
Most scientific institutions acknowledge the importance of opening the so-called 'ivory tower' of academic research through popularization, industrial collaboration or teaching. Ho…
The mass-radius relationship from solar-type stars to terrestrial planets: a review
G. Chabrier, I. Baraffe, J. Leconte +2
In this review, we summarize our present knowledge of the behaviour of the mass-radius relationship from solar-type stars down to terrestrial planets, across the regime of substell…
Enhanced stochastic oscillations in autocatalytic reactions
Thierry Dauxois, Francesca Di Patti, Duccio Fanelli +1
We study a simplified scheme of coupled autocatalytic reactions, previously introduced by Togashi and Kaneko. The role of stochastic fluctuations is elucidated through the use…
A new distance for high level RNA secondary structure comparison
Julien Allali, Marie-France Sagot
We describe an algorithm for comparing two RNA secondary structures coded in the form of trees that introduces two new operations, called node fusion and edge fusion, besides the t…
Evolution of very low mass pre-main sequence stars and young brown dwarfs under accretion: A phenomenological approach
Jose Gallardo, Isabelle Baraffe, Gilles Chabrier
In the poster presented in Cool Star 15, we analyzed the effect of disk accretion on the evolution of very low mass pre-main sequence stars and young brown dwarfs and the resulting…
