Resonant demagnetization of a dipolar BEC in a 3D optical lattice
A. de Paz, A. Chotia, E. Marechal +4
We study dipolar relaxation of a chromium BEC loaded into a 3D optical lattice. We observe dipolar relaxation resonances when the magnetic energy released during the inelastic coll…
Stability estimates for the Radon transform with restricted data and applications
Pedro Caro, David Dos Santos Ferreira, Alberto Ruiz
In this article, we prove a stability estimate going from the Radon transform of a function with limited angle-distance data to the norm of the function itself, under some co…
An algebraic model for finite loop spaces
Carles Broto, Ran Levi, Bob Oliver
The theory of p-local compact groups, developed in an earlier paper by the same authors, is designed to give a unified framework in which to study the p-local homotopy theory of cl…
Intrinsic switching field distribution of arrays of Ni80Fe20 nanowires probed by magnetic force microscopy
M. R. Tabasum, F. Zighem, J. De La Torre Medina +2
The progress of magnetization reversal of weakly packed ferromagnetic Ni80Fe20 nanowire arrays of different diameters (40, 50, 70 and 100 nm) electrodeposited in polycarbonate memb…
Intermediate extension of Chow motives of Abelian type
Jörg Wildeshaus
In this article, we give an unconditional construction of a motivic analogue of the intermediate extension in the context of Chow motives of Abelian type. Our main application conc…
Combinatorial Hopf algebraic description of the multiscale renormalization in quantum field theory
Thomas Krajewski, Vincent Rivasseau, Adrian Tanasa
We define in this paper several Hopf algebras describing the combinatorics of the so-called multi-scale renormalization in quantum field theory. After a brief recall of the main ma…
