All in one: holographic microscopy unveils bacterial transport from single cells to population
Lucie Klopffer, S. Becker, Laurence Mathieu +1
Prior to pioneer surface adhesion, bacteria have to navigate in flows, often in confined environments. While much is known about their individual swimming dynamics, our understandi…
An Abelian Higgs model for disclinations in nematics
A. de Pádua Santos, F. Moraes, F. A. N. Santos +1
Topological defects in elastic media may be described by a geometric field akin to three-dimensional gravity. From this point of view, disclinations are line defects of zero width…
Interaction of ammonium with birnessite: Evidence of a chemical and structural transformation in alkaline aqueous medium
Hella Boumaiza, Romain Coustel, Christelle Despas +2
The ammonium cation interaction with Na-birnessite in aqueous alkaline medium was studied. Solution and solid analysis give evidence that birnessite is not only acting as a cationi…
Conditions for the formation of pure birnessite during the oxidation of Mn(II) cations in aqueous alkaline medium
Hella Boumaiza, Romain Coustel, Ghouti Medjahdi +2
Birnessite was synthetized through redox reaction by mixing MnO4-, Mn2+ and OH- solutions. The Mn(VII): Mn(II) ratio of 0.33 was chosen and three methods were used consisting in a…
Covalent Functionalization of HiPco Single-Walled Carbon Nanotubes: Differences in the Oxidizing Action of H2SO4 and HNO3 during a Soft Oxidation Process
Xavier Devaux, Brigitte Vigolo, Edward Mcrae +7
The results of a study on the evolution of HiPco single-walled carbon nanotubes during the oxidizing action of H2SO4 and HNO3 are presented. The process conditions used have been c…
Preliminary Synthesis of Carbon Nitride Thin Films by N/CH Microwave Plasma Assisted Chemical Vapour Deposition: Characterisation of the Discharge and the Obtained Films
Paul Kouakou, Valerie Brien, Badreddine Assouar +4
The present work deals with the synthesis of crystalline carbon nitride thin films by microwave plasma assisted chemical vapour deposition in N/CH gas mixture. The discharg…
Reflexion Mössbauer analysis of the in situ oxidation products hydroxycarbonate green rust
Sebastien Naille, Mustapha Abdelmoula, Didier Louber +2
The purpose of this study is to determine the nature of the oxidation products of FeII-III hydroxycarbonate FeII4FeIII2(OH)12CO3~3H2O (green rust GR(CO32-)) by using the miniaturis…
On the critical behavior of two-dimensional liquid crystals
Ana Isabel Fariñas-Sánchez, Robert Botet, Bertrand Berche +1
The Lebwohl-Lasher (LL) model is the traditional model used to describe the nematic-isotropic transition of real liquid crystals. In this paper, we develop a numerical study of the…
Bayesian separation of spectral sources under non-negativity and full additivity constraints
Nicolas Dobigeon, Said Moussaoui, Jean-Yves Tourneret +1
This paper addresses the problem of separating spectral sources which are linearly mixed with unknown proportions. The main difficulty of the problem is to ensure the full additivi…
Entanglement evolution after connecting finite to infinite quantum chains
V. Eisler, D. Karevski, T. Platini +1
We study zero-temperature XX chains and transverse Ising chains and join an initially separate finite piece on one or on both sides to an infinite remainder. In both critical and n…
Absence of logarithmic scaling in the ageing behaviour of the 4D spherical model
Maximilian Ebbinghaus, Helene Grandclaude, Malte Henkel
The non-equilibrium dynamics of the kinetic spherical model, quenched to T<=T_c, with a non-conserved order-parameter is studied at its upper critical dimension d=d*=4. In the scal…
Relaxation in the XX quantum chain
Thierry Platini, Dragi Karevski
We present the results obtained on the magnetisation relaxation properties of an XX quantum chain in a transverse magnetic field. We first consider an initial thermal kink-like sta…
Gradient critical phenomena in the Ising quantum chain
Thierry Platini, Dragi Karevski, Loïc Turban
We consider the behaviour of a critical system in the presence of a gradient perturbation of the couplings. In the direction of the gradient an interface region separates the order…
Ageing, dynamical scaling and its extensions in many-particle systems without detailed balance
Malte Henkel
Recent studies on the phenomenology of ageing in certain many-particle systems which are at a critical point of their non-equilibrium steady-states, are reviewed. Examples include…
Historical and interpretative aspects of quantum mechanics: a physicists' naive approach
B. Berche, C. Chatelain, C. Dufour +2
Many theoretical predictions derived from quantum mechanics have been confirmed experimentally during the last 80 years. However, interpretative aspects have long been subject to d…
Probability distributions of the work in the 2D-Ising model
Christophe Chatelain, Dragi Karevski
Probability distributions of the magnetic work are computed for the 2D Ising model by means of Monte Carlo simulations. The system is first prepared at equilibrium for three temper…
Ageing in the critical contact process: a Monte Carlo study
Jose J. Ramasco, Malte Henkel, Maria Augusta Santos +1
The long-time dynamics of the critical contact process which is brought suddenly out of an uncorrelated initial state undergoes ageing in close analogy with quenched magnetic syste…
On universality in aging ferromagnets
Christophe Chatelain
This work is a contribution to the study of universality in out-of-equilibrium lattice models undergoing a second-order phase transition at equilibrium. The experimental protocol t…
Local scale-invariance and ageing in noisy systems
Alan Picone, Malte Henkel
The influence of the noise on the long-time ageing dynamics of a quenched ferromagnetic spin system with a non-conserved order parameter and described through a Langevin equation w…
Scaling of the linear response in simple ageing systems without disorder
Malte Henkel, Matthias Paessens, Michel Pleimling
The time-dependent scaling of the thermoremanent and zero-field-cooled susceptiblities in ferromagnetic spin systems undergoing ageing after a quench to a temperature at or below c…
Universal crossing probabilities and incipient spanning clusters in directed percolation
L. Turban
Shape-dependent universal crossing probabilities are studied, via Monte Carlo simulations, for bond and site directed percolation on the square lattice in the diagonal direction, a…
Scale-invariant universal crossing probability in one-dimensional diffusion-limited coalescence
L. Turban
The crossing probability in the time direction is defined for an off-equilibrium reaction-diffusion system as the probability that the system of size L is still active at time t, i…
