Radiative hydrodynamics simulations of red supergiant stars. III. Spectro-photocentric variability, photometric variability, and consequences on Gaia measurements
A. Chiavassa, E. Pasquato, A. Jorissen +8
Context. It has been shown that convection in red supergiant stars gives rise to large granules causing surface inhomogeneities together with shock waves in the photosphere. The re…
Modified spin-wave theory with ordering vector optimization II: Spatially anisotropic triangular lattice and model with Heisenberg interactions
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We study the ground state phases of the Heisenberg quantum antiferromagnet on the spatially anisotropic triangular lattice and on the square lattice with up to next-next-ne…
Rotational intermittency and turbulence induced lift experienced by large particles in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
The motion of a large, neutrally buoyant, particle, freely advected by a turbulent flow is determined experimentally. We demonstrate that both the translational and angular acceler…
Shear-induced structuration of confined carbon black gels: Steady-state features of vorticity-aligned flocs
Vincent Grenard, Nicolas Taberlet, Sebastien Manneville
Various dispersions of attractive particles are known to aggregate into patterns of vorticity-aligned stripes when sheared in confined geometries. We report a thorough experimental…
Carbon nanotubes adhesion and nanomechanical behavior from peeling force spectroscopy
Julien Buchoux, Ludovic Bellon, Sophie Marsaudon +1
Applications based on Single Walled Carbon Nanotube (SWNT) are good example of the great need to continuously develop metrology methods in the field of nanotechnology. Contact and…
Existence and a priori bounds for electrostatic Klein-Gordon-Maxwell systems in fully inhomogeneous spaces
Olivier Druet, Emmanuel Hebey
We prove existence and uniform bounds for electrostatic Klein-Gordon-Maxwell systems in the inhomogeneous context of a compact Riemannian manifold when the mass potential, balanced…
Beyond-mean-field theories with zero-range effective interactions. A way to handle the ultraviolet divergence
K. Moghrabi, M. Grasso, G. Colò +1
Zero-range effective interactions are commonly used in nuclear physics and in other domains to describe many-body systems within the mean-field model. If they are used within a bey…
Support convergence in the single ring theorem
Alice Guionnet, Ofer Zeitouni
We study the eigenvalues of non-normal square matrices of the form A_n=U_nT_nV_n with U_n,V_n independent Haar distributed on the unitary group and T_n real diagonal. We show that…
Microstructure from ferroelastic transitions using strain pseudospin clock models in two and three dimensions: a local mean-field analysis
Romain Vasseur, Turab Lookman, Subodh R. Shenoy
We show how microstructure can arise in first-order ferroelastic structural transitions, in two and three spatial dimensions, through a local meanfield approximation of their pseud…
The Atlas3D project -- I. A volume-limited sample of 260 nearby early-type galaxies: science goals and selection criteria
Michele Cappellari, Eric Emsellem, Davor Krajnovic +23
The Atlas3D project is a multi-wavelength survey combined with a theoretical modeling effort. The observations span from the radio to the millimeter and optical, and provide multi-…
Quasi-polynomial mixing of the 2D stochastic Ising model with "plus" boundary up to criticality
Eyal Lubetzky, Fabio Martinelli, Allan Sly +1
We considerably improve upon the recent result of Martinelli and Toninelli on the mixing time of Glauber dynamics for the 2D Ising model in a box of side at low temperature and…
Understanding exoplanet formation, structure and evolution in 2010
G. Chabrier, J. Leconte, I. Baraffe
In this short review, we summarize our present understanding (and non-understanding) of exoplanet formation, structure and evolution, in the light of the most recent discoveries. R…
Longitudinal and Transverse structure functions in high Reynolds-number turbulence
Rainer Grauer, Holger Homann, Jean-Francois Pinton
Using exact relations between velocity structure functions (Hill, Hill and Boratav, and Yakhot) and neglecting pressure contributions in a first approximation, we obtain a closed s…
A Type System for the Vectorial Aspect of the Linear-Algebraic Lambda-Calculus
Pablo Arrighi, Alejandro Díaz-Caro, Benoît Valiron
We describe a type system for the linear-algebraic lambda-calculus. The type system accounts for the part of the language emulating linear operators and vectors, i.e. it is able to…
Review of AdS/CFT Integrability, Chapter II.3: Sigma Model, Gauge Fixing
Marc Magro
This review is devoted to the classical integrability of the AdS5xS5 superstring theory. It starts with a reminder of the corresponding action as a coset model. The symmetries of t…
Review of AdS/CFT Integrability: An Overview
Niklas Beisert, Changrim Ahn, Luis F. Alday +23
This is the introductory chapter of a review collection on integrability in the context of the AdS/CFT correspondence. In the collection we present an overview of the achievements…
Linearization effect in multifractal analysis: Insights from the Random Energy Model
Florian Angeletti, Marc Mézard, Eric Bertin +1
The analysis of the linearization effect in multifractal analysis, and hence of the estimation of moments for multifractal processes, is revisited borrowing concepts from the stati…
Two-Point Vorticity Statistics in the Inverse Turbulent Cascade
R. Friedrich, M. Voßkuhle, O. Kamps +1
We present a statistical analysis of the two-point vorticity probability density of the vorticity field generated in the inverse cascade of stationary two-dimensional turbulence.
The impact of supernovae driven winds on stream-fed protogalaxies
Leila C. Powell, Adrianne Slyz, Julien Devriendt
SNe driven winds are widely thought to be very influential in the high-redshift Universe, shaping the properties of the circum-galactic medium, enriching the IGM with metals and dr…
Self-consistent inhomogeneous steady states in Hamiltonian mean field dynamics
Pierre de Buyl, David Mukamel, Stefano Ruffo
Long-lived quasistationary states, associated with stationary stable solutions of the Vlasov equation, are found in systems with long-range interactions. Studies of the relaxation…
On the Magical Supergravities in Six Dimensions
M. Gunaydin, H. Samtleben, E. Sezgin
Magical supergravities are a very special class of supergravity theories whose symmetries and matter content in various dimensions correspond to symmetries and underlying algebraic…

Thibaut Divoux, Catherine Barentin, Sébastien Manneville
Stress-induced fluidization of a simple yield stress fluid, namely a carbopol microgel, is addressed through extensive rheological measurements coupled to simultaneous temporally a…
Loop models, random matrices and planar algebras
A. Guionnet, V. F. R. Jones, D. Shlyakhtenko +1
We define matrix models that converge to the generating functions of a wide variety of loop models with fugacity taken in sets with an accumulation point. The latter can also be se…
Invited review: Effect of temperature on a granular pile
Thibaut Divoux
As a fragile construction, a granular pile is very sensitive to minute external perturbations. In particular, it is now well established that a granular assembly is sensitive to va…
