The baryon acoustic oscillation peak: a flexible standard ruler
Boudewijn F. Roukema
For about a decade, the baryon acoustic oscillation (BAO) peak at about 105 Mpc/h has provided a standard ruler test of the LCDM cosmological model, a member of the Friedmann--Lema…
Stochastic dynamics of particles trapped in turbulent flows
N Machicoane, M López-Caballero, L Fiabane +4
The long time dynamics of large particles trapped in two inhomogeneous turbulent shear flows is studied experimentally. Both flows present a common feature, a shear region that sep…
Lagrangian velocity and acceleration correlations of large inertial particles in a closed turbulent flow
Nathanaël Machicoane, Romain Volk
We investigate the response of large inertial particle to turbulent fluctuations in a inhomogeneous and anisotropic flow. We conduct a Lagrangian study using particles both heavier…
Structure of Titan's evaporites
D. Cordier, T. Cornet, J. W. Barnes +5
Numerous geological features that could be evaporitic in origin have been identified on the surface of Titan. Although they seem to be water-ice poor, their main properties -chemic…
Asymptotically hyperbolic connections
Joel Fine, Yannick Herfray, Kirill Krasnov +1
General Relativity in 4 dimensions can be equivalently described as a dynamical theory of SO(3)-connections rather than metrics. We introduce the notion of asymptotically hyperboli…
From thermal rectifiers to thermoelectric devices
Giuliano Benenti, Giulio Casati, Carlos Mejia-Monasterio +1
We discuss thermal rectification and thermoelectric energy conversion from the perspective of nonequilibrium statistical mechanics and dynamical systems theory. After preliminary c…
Theoretical limits on magnetic field strengths in low-mass stars
Matthew K. Browning, Maria A. Weber, Gilles Chabrier +1
Observations have suggested that some low-mass stars have larger radii than predicted by 1-D structure models. Some theoretical models have invoked very strong interior magnetic fi…
A statistical physics viewpoint on the dynamics of the bouncing ball
Jean-Yonnel Chastaing, Jean-Christophe Géminard, Eric Bertin
We study from a statistical physics perspective the dynamics of a bouncing ball maintained in a chaotic regime thanks to collisions with a plate experiencing an aperiodic vibration…
Local Oscillatory Rheology from Echography
Brice Saint-Michel, Thomas Gibaud, Mathieu Leocmach +1
Local Oscillatory Rheology from Echography (LORE) consists in a traditional rheology experiment synchronized with high-frequency ultrasonic imaging which gives access to the local…
A Jacobian-free Newton-Krylov method for time-implicit multidimensional hydrodynamics
Maxime Viallet, Tom Goffrey, Isabelle Baraffe +5
This work is a continuation of our efforts to develop an efficient implicit solver for multidimensional hydrodynamics for the purpose of studying important physical processes in st…
The first Galaxy scale hunt for the youngest high-mass protostars
T. Csengeri, S. Bontemps, F. Wyrowski +17
The origin of massive stars is a fundamental open issue in modern astrophysics. Pre-ALMA interferometric studies reveal precursors to early B to late O type stars with collapsing e…
From volume cone to metric cone in the nonsmooth setting
Nicola Gigli, Guido de Philippis
We prove that `volume cone implies metric cone' in the setting of RCD spaces, thus generalising to this class of spaces a well known result of Cheeger-Colding valid in Ricci-limit…
Boundary of the action of Thompson group F on dyadic numbers
Pavlo Mishchenko
We prove that the Poisson boundary of a simple random walk on the Schreier graph of action of on , where is the set of dyadic numbers in , is n…
On the Green and Wald formalism
Jan J. Ostrowski, Boudewijn F. Roukema
Backreaction in the cosmological context is a longstanding problem that is especially important in the present era of precise cosmology. The standard model of a homogeneous backgro…
Finite-size scaling of the magnetization probability density for the critical Ising model in slab geometry
David Lopes Cardozo, Peter C. W. Holdsworth
The magnetization probability density in d=2 and 3 dimensional Ising models in slab geometry of volume is computed through Monte-Carlo simula…
The spread of infections on evolving scale-free networks
Emmanuel Jacob, Peter Mörters
We study the contact process on a class of evolving scale-free networks, where each node updates its connections at independent random times. We give a rigorous mathematical proof…
From the geometry of box spaces to the geometry and measured couplings of groups
Kajal Das
In this paper, we prove that if two `box spaces' of two residually finite groups are coarsely equivalent, then the two groups are `uniform measured equivalent' (UME). More generall…
Out-of-equilibrium fluctuations in stochastic long-range interacting systems
Shamik Gupta, Thierry Dauxois, Stefano Ruffo
For a many-particle system with long-range interactions and evolving under stochastic dynamics, we study for the first time the out-of-equilibrium fluctuations of the work done on…
Engineered swift equilibration of a Brownian particle
Ignacio Martinez, Artyom Petrosyan, David Guéry-Odelin +2
A fundamental and intrinsic property of any device or natural system is its relaxation time relax, which is the time it takes to return to equilibrium after the sudden change of a…
Super-linear spreading in local and non-local cane toads equations
Emeric Bouin, Christopher Henderson, Lenya Ryzhik
In this paper, we show super-linear propagation in a nonlocal reaction-diffusion-mutation equation modeling the invasion of cane toads in Australia that has attracted attention rec…
A Sharp Condition for Exact Support Recovery of with Orthogonal Matching Pursuit
Jinming Wen, Zhengchun Zhou, Jian Wang +2
Support recovery of sparse signals from noisy measurements with orthogonal matching pursuit (OMP) has been extensively studied. In this paper, we show that for any -sparse signa…
Predicting Climate Change using Response Theory: Global Averages and Spatial Patterns
Valerio Lucarini, Frank Lunkeit, Francesco Ragone
The provision of accurate methods for predicting the climate response to anthropogenic and natural forcings is a key contemporary scientific challenge. Using a simplified and effic…
Diffusiophoresis at the macroscale
Cyril Mauger, Romain Volk, Nathanael Machicoane +4
Diffusiophoresis, a ubiquitous phenomenon that induces particle transport whenever solute concentration gradients are present, was recently observed in the context of microsystems…
Observational Challenges for the Standard FLRW Model
Thomas Buchert, Alan A. Coley, Hagen Kleinert +2
We summarise some of the main observational challenges for the standard Friedmann-Lemaitre-Robertson-Walker cosmological model and describe how results recently presented in the pa…
