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…
Carleman estimates for elliptic operators with jumps at an interface: Anisotropic case and sharp geometric conditions
Jérôme Le Rousseau, Nicolas Lerner
We consider a second-order selfadjoint elliptic operator with an anisotropic diffusion matrix having a jump across a smooth hypersurface. We prove the existence of a weight-functio…
Efficient Radio Frequency filters for space constrained cryogenic set-ups
Soumen Mandal, Tobias Bautze, Remi Blinder +3
Noise filtering is an essential part for measurement of quantum phenomena at extremely low temperatures. Here, we present the design of a filter which can be installed in space con…
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…
Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
Sylvain Guiriec, Valerie Connaughton, Michael S. Briggs +29
Observations of GRB 100724B with the Fermi Gamma-Ray Burst Monitor (GBM) find that the spectrum is dominated by the typical Band functional form, which is usually taken to represen…
Remanence effects in the electrical resistivity of spin glasses
Thibaut Capron, A. Perrat-Mabilon, Christophe Peaucelle +5
We have measured the low temperature electrical resistivity of Ag : Mn mesoscopic spin glasses prepared by ion implantation with a concentration of 700 ppm. As expected, we observe…
Remarks on the Minimizing Geodesic Problem in Inviscid Incompressible Fluid Mechanics
Yann Brenier
We consider minimizing geodesics along the group of volume preserving maps of a given 3-dimensional domain . The corresponding curves describe the motion of an…
Discussions on "Riemann manifold Langevin and Hamiltonian Monte Carlo methods"
Simon Barthelme, Magali Beffy, Nicolas Chopin +5
This is a collection of discussions of `Riemann manifold Langevin and Hamiltonian Monte Carlo methods" by Girolami and Calderhead, to appear in the Journal of the Royal Statistical…
From the Ginzburg-Landau model to vortex lattice problems
Etienne Sandier, Sylvia Serfaty
We study minimizers of the two-dimensional Ginzburg-Landau energy with applied magnetic field, between the first and second critical fields. In this regime, minimizing configuratio…
Thermally activated intersubband scattering and oscillating magnetoresistance in quantum wells
S. Wiedmann, G. M. Gusev, O. E. Raichev +2
Experimental studies of magnetoresistance in high-mobility wide quantum wells reveal oscillations which appear with an increase in temperature to 10 K and whose period is close to…
Specific-heat measurements of superconducting NbS2 single crystal in an external magnetic field: Study on the energy gap structure
J. Kacmarcik, Z. Pribulova, C. Marcenat +4
The heat capacity of a 2H-NbS2 single crystal has been measured by a highly sensitive ac technique down to 0.6 K and in magnetic fields up to 14 T. At very low temperatures data sh…
Third-order Elsässer moments in axisymmetric MHD turbulence
Sebastien Galtier
Incompressible MHD turbulence is investigated under the presence of a uniform magnetic field $\bb0$. Such a situation is described in the correlation space by a divergence relation…

T. Klein, D. Braithwaite, A. Demuer +8
We report on specific heat (), transport, Hall probe and penetration depth measurements performed on Fe(SeTe) single crystals ( K). The thermodyna…
Minimizers of the Lawrence-Doniach Functional with Oblique Magnetic Fields
Stan Alama, Lia Bronsard, Étienne Sandier
We study minimizers of the Lawrence--Doniach energy, which describes equilibrium states of superconductors with layered structure, assuming Floquet-periodic boundary conditions. Sp…

We have studied the distinctive features of the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) instability and phase transitions in two--dimensional (2D) mesoscopic superconductors placed…
Conductivity and the current-current correlation measure
J. M. Combes, F. Germinet, P. D. Hislop
We review various formulations of conductivity for one-particle Hamiltonians and relate them to the current-current correlation measure. We prove that the current-current correlati…
Gamma-Ray Emission Concurrent with the Nova in the Symbiotic Binary V407 Cygni
LAT Collaboration
Novae are thermonuclear explosions on a white dwarf surface fueled by mass accreted from a companion star. Current physical models posit that shocked expanding gas from the nova sh…
