Electrical detection of spin accumulation in a p-type GaAs quantum well
R. Mattana, J. -M. George, H. Jaffres +5
We report on experiments in which a spin-polarized current is injected from a ferromagnetic electrode into a quantum well through an AlAs barrier. The resulting spi…
Compaction dynamics of a granular media under vertical tapping
P. Philippe, D. Bideau
We report new experimental results on granular compaction under consecutive vertical taps. The evolution of the mean volume fraction and of the mean potential energy of a granular…
Neutral-ionic phase transition : a thorough ab-initio study of TTF-CA
V. Oison, C. Katan, P. Rabiller +2
The prototype compound for the neutral-ionic phase transition, namely TTF-CA, is theoretically investigated by first-principles density functional theory calculations. The study is…
Thermodynamics of fiber bundles
Steven R. Pride, Renaud Toussaint
A recent theory that determines the properties of disordered solids as the solid accumulates damage is applied to the special case of fiber bundles with global load sharing and is…
Fracture of disordered solids in compression as a critical phenomenon: III. Analysis of the localization transition
Renaud Toussaint, Steven R. Pride
The properties of the Hamiltonian developed in Paper II are studied showing that at a particular strain level a ``localization'' phase transition occurs characterized by the emerge…
Fracture of disordered solids in compression as a critical phenomenon: II. Model Hamiltonian for a population of interacting cracks
Renaud Toussaint, Steven R. Pride
To obtain the probability distribution of 2D crack patterns in mesoscopic regions of a disordered solid, the formalism of Paper I requires that a functional form associating the cr…
Fracture of disordered solids in compression as a critical phenomenon: I. Statistical mechanics formalism
Renaud Toussaint, Steven R. Pride
This is the first of a series of three articles that treats fracture localization as a critical phenomenon. This first article establishes a statistical mechanics based on ensemble…
Large time behavior for vortex evolution in the half-plane
D. Iftimie, M. C. Lopes Filho, H. J. Nussenzveig Lopes
In this article we study the long-time behavior of incompressible ideal flow in a half plane from the point of view of vortex scattering. Our main result is that certain asymptotic…
Dynamics of modulated and composite aperiodic crystals: the signature of the inner polarization in the neutron coherent inelastic scattering
O. Radulescu, T. Janssen, J. Etrillard
We compare within an unifying formalism the dynamical properties of modulated and composite aperiodic (incommensurate) crystals. We discuss the concept of inner polarization and we…
Sur la R-équivalence de torseurs sous un groupe fini
Laurent Moret-Bailly
We give criteria for R-equivalence of torsors under finite constant group schemes over a field. In paticular, using bitorsors, we obtain a Galois devissage result which formalises…
Connected components of the moduli spaces of Abelian differentials with prescribed singularities
M. Kontsevich, A. Zorich
Consider the moduli space of pairs (C,w) where C is a smooth compact complex curve of a given genus and w is a holomorphic 1-form on C with a given list of multiplicities of zeroes…
