Formation of femtosecond laser induced surface structures on silicon : insights from numerical modeling and single pulse experiments
Thibault J. Y. Derrien, Rémi Torres, Thierry Sarnet +2
Laser induced periodic surface structures (LIPSS) are formed by multiple irradiation of femtosecond laser on a silicon target. In this paper, we focus and discuss the surface plasm…
Quasi-static magnetohydrodynamic turbulence at high Reynolds number
B. F. N. Favier, F. S. Godeferd, C. Cambon +2
We analyse the anisotropy of homogeneous turbulence in an electrically conducting fluid submitted to a uniform magnetic field, for low magnetic Reynolds number, in the quasi- stati…
Calabi-Yau algebras viewed as deformations of Poisson algebras
Roland Berger, Anne Pichereau
We define a family of 3-Calabi-Yau algebras by potentials. For some of these algebras, we explicitly compute the Hochschild homology with the help of Poisson homology. The point is…
The FENE dumbbell polymer model: existence and uniqueness of solutions for the momentum balance equation
Adriana Valentina Busuioc, Ionel Sorin Ciuperca, Dragos Iftimie +1
We consider the FENE dumbbell polymer model which is the coupling of the incompressible Navier-Stokes equations with the corresponding Fokker-Planck-Smoluchowski di ffusion equatio…
On the two-dimensionalization of quasistatic magnetohydrodynamic turbulence
Benjamin F. N. Favier, Fabien S. Godeferd, Claude Cambon +1
We analyze the anisotropy of turbulence in an electrically conducting fluid in the presence of a uniform magnetic field, for low magnetic Reynolds number, using the quasi-static ap…
Zonal shear and super-rotation in a magnetized spherical Couette flow experiment
Daniel Brito, Thierry Alboussière, Philippe Cardin +6
We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The in…
