Master singular behavior from correlation length measurements for seven one-component fluids near their gas-liquid critical point
Yves Garrabos, Fabien Palencia, Carole Lecoutre-Chabot +2
We present the master (i.e. unique) behavior of the correlation length, as a function of the thermal field along the critical isochore, asymptotically close to the gas-liquid criti…
A ring trap for ultracold atoms
Olivier Morizot, Yves Colombe, Vincent Lorent +2
We propose a new kind of toroidal trap, designed for ultracold atoms. It relies on a combination of a magnetic trap for rf-dressed atoms, which creates a bubble-like trap, and a st…
Laser spectroscopy with nanometric gas cells : distance dependence of atom-surface interaction and collisions under confinement
Ismahène Hamdi, Petko Todorov, Alexander Yarovitski +11
The high sensitivity of Laser Spectroscopy has made possible the exploration of atomic resonances in newly designed "nanometric" gas cells, whose local thickness varies from 20nm t…
Estimates for the density of a nonlinear Landau process
Hélène Guérin, Sylvie Méléard, Eulalia Nualart
The aim of this paper is to obtain estimates for the density of the law of a specific nonlinear diffusion process at any positive bounded time. This process is issued from kinetic…
Sur le statut référentiel des entités nommées
Thierry Poibeau
We show in this paper that, on the one hand, named entities can be designated using different denominations and that, on the second hand, names denoting named entities are polysemo…
Diophantus' 20th Problem and Fermat's Last Theorem for n=4: Formalization of Fermat's Proofs in the Coq Proof Assistant
David Delahaye, Micaela Mayero
We present the proof of Diophantus' 20th problem (book VI of Diophantus' Arithmetica), which consists in wondering if there exist right triangles whose sides may be measured as int…
Dichotomies between uniform hyperbolicity and zero Lyapunov exponents for SL(2,R) cocycles
Jairo Bochi, Bassam Fayad
We consider the linear cocycle induced by a measure preserving dynamical system and a map . We address the dependence of the…
Context Semantics, Linear Logic and Computational Complexity
Ugo Dal Lago
We show that context semantics can be fruitfully applied to the quantitative analysis of proof normalization in linear logic. In particular, context semantics lets us define the we…
Conjecture de l'inertie modérée de Serre
Xavier Caruso
Let K be a local field of mixte characteristics. We assume that the residue field is perfect. Let X\_K be a proper smooth scheme over K admitting an integer model X which is proper…
A Bose-Einstein condensate bouncing off a rough mirror
Hélène Perrin, Yves Colombe, Brigitte Mercier +2
We present experimental results and theoretical analysis of the diffuse reflection of a Bose-Einstein condensate from a rough mirror. The mirror is produced by a blue-detuned evane…
Lifshitz Tails in Constant Magnetic Fields
Frédéric Klopp, Georgi Raikov
We consider the 2D Landau Hamiltonian perturbed by a random alloy-type potential, and investigate the Lifshitz tails, i.e. the asymptotic behavior of the corresponding integrat…
Absolute frequency measurement of an SF6 two-photon line using a femtosecond optical comb and sum-frequency generation
Anne Amy-Klein, Andrei Goncharov, Mickael Guinet +4
We demonstrate a new simple technique to measure IR frequencies near 30 THz using a femtosecond (fs) laser optical comb and sum-frequency generation. The optical frequency is direc…
On the ergodicity of the Weyl sums cocycle
Bassam Fayad
For , we consider the map $T_\a: \T^2 \to \T^2$ given by . The skew product $f_\a: \T^2 \times \C \to \T^2 \times \C$ given by $f_θ(x,y,z)=(T_θ(x…
A Computational Solution to a Question by Beauville on the Invariants of the Binary Quintic
Abdelmalek Abdesselam
We obtain an alternate proof of an injectivity result by Beauville for a map from the moduli space of quartic del Pezzo surfaces to the set of conjugacy classes of certain subgroup…
A detector for continuous measurement of ultra-cold atoms in real time
C. Figl, L. Longchambon, M. Jeppesen +4
We present the first detector capable of recording high-bandwidth real time atom number density measurements of a Bose Einstein condensate. Based on a two-color Mach-Zehnder interf…
On the critical pair theory in Z/pZ
Yahya Ould Hamidoune, Oriol Serra, Gilles Zemor
Let A and B be subsets of Z/pZ such that |A+B| < |A|+|B|+2. We prove that, if |A|>3, |B|>4, |A+B|<p-4 and p > 52, then A and B are included in arithmetic progressions with the same…
Long-distance frequency dissemination with a resolution of 10-17
Christophe Daussy, Olivier Lopez, Anne Amy-Klein +11
We use a new technique to disseminate microwave reference signals along ordinary optical fiber. The fractional frequency resolution of a link of 86 km in length is 10-17 for a one…
Dicke Coherent Narrowing in Two-Photon and Raman Spectroscopy of Thin Vapour Cells
Gabriel Dutier, Petko Todorov, Ismahène Hamdi +4
The principle of coherent Dicke narrowing in a thin vapour cell, in which sub-Doppler spectral lineshapes are observed under a normal irradiation for a l/2 thickness, is generalize…
Time-Resolved Diffusing Wave Spectroscopy for selected photon paths beyond 300 transport mean free paths
Jean-Michel Tualle, Ha Lien Nghiem, Monia Cheikh +3
This paper is devoted to the theoretical and experimental demonstration of the possibility to perform time-resolved diffusing wave spectroscopy: we successfully registered field fl…
Multilevel expander codes
Alexander Barg, Gilles Zemor
We define multilevel codes on bipartite graphs that have properties analogous to multilevel serial concatenations. A decoding algorithm is described that corrects a proportion of e…
Strong resonant tunneling, level repulsion and spectral type for one-dimensional adiabatic quasi-periodic Schrödinger operators
Alexander Fedotov, Frédéric Klopp
In this paper, we consider one dimensional adiabatic quasi-periodic Schrödinger operators in the regime of strong resonant tunneling. We show the emergence of a level repulsion phe…
