Spin tunneling in junctions with disordered ferromagnets
P. V. Paluskar, J. J. Attema, G. A. de Wijs +6
We provide compelling evidence to establish that, contrary to one's elementary guess, the tunneling spin polarization (TSP) of amorphous CoFeB is larger than that of highly texture…
Spatial coupling of particle and fluid models for streamers: where nonlocality matters
Chao Li, Ute Ebert, W. J. M. Brok +1
Particle models for streamer ionization fronts contain correct electron energy distributions, runaway effects and single electron statistics. Conventional fluid models are computat…
Avalanche to streamer transition in particle simulations
Chao Li, Ute Ebert, W. J. M. Brok
The avalanche to streamer transition is studied and illustrated in a particle model. The results are similar to those of fluid models. However, when super-particles are introduced,…
A preliminary study of asymmetric vocal fold vibrations: modeling and "in-vitro" validation
Nicolas Ruty, Annemie Van Hirtum, Xavier Pelorson +2
This paper deals with some of aspects of the influence of asymmetry on vocal folds vibrations. A theoretical model of vocal fold asymmetry is presented. The influence of asymmetry…
Large deviations for eigenvalues of sample covariance matrices, with applications to mobile communication systems
Anne Fey, Remco van der Hofstad, Marten Klok
We study sample covariance matrices of the form , where is a matrix with i.i.d. mean zero entries. This is a generalization of so-called Wishart m…
Uniqueness, intractability and exact algorithms: reflections on level-k phylogenetic networks
Leo van Iersel, Steven Kelk, Matthias Mnich
Phylogenetic networks provide a way to describe and visualize evolutionary histories that have undergone so-called reticulate evolutionary events such as recombination, hybridizati…
Interaction of streamers in air and other oxygen-nitrogen mixtures
A. Luque, U. Ebert, W. Hundsdorfer
The interaction of streamers in nitrogen-oxygen mixtures such as air is studied. First, an efficient method for fully three-dimensional streamer simulations in multiprocessor machi…
Analytic models of ultra-cold atomic collisions at negative energies for application to confinement-induced resonances
S. G. Bhongale, S. J. J. M. F. Kokkelmans, Ivan H. Deutsch
We construct simple analytic models of the -matrix, accounting for both scattering resonances and smooth background contributions for collisions that occur below the s-wave thre…
The dynamics of non-linear optical absorption
D. Corbett, C. L. van Oosten, M. Warner
On traversing materials with absorbing dyes, weak optical beams develop a Beer (exponential) profile, while intense beams develop a spatially initially linear and then finally an e…
Modeling the pressure Hessian and viscous Laplacian in Turbulence: comparisons with DNS and implications on velocity gradient dynamics
L. Chevillard, C. Meneveau, L. Biferale +1
Modeling the velocity gradient tensor A along Lagrangian trajectories in turbulent flow requires closures for the pressure Hessian and viscous Laplacian of A. Based on an Eulerian-…
Mean-field behavior for long- and finite range Ising model, percolation and self-avoiding walk
Markus Heydenreich, Remco van der Hofstad, Akira Sakai
We consider self-avoiding walk, percolation and the Ising model with long and finite range. By means of the lace expansion we prove mean-field behavior for these models if $d>2(α\w…
Collisional properties of weakly bound heteronuclear dimers
B. Marcelis, S. J. J. M. F. Kokkelmans, G. V. Shlyapnikov +1
We consider collisional properties of weakly bound heteronuclear molecules (dimers) formed in a two-species mixture of atoms with a large mass difference. We focus on dimers contai…
Simple Lie Algebras having Extremal Elements
Arjeh M. Cohen, Gabor Ivanyos, Dan A. Roozemond
Let L be a simple finite-dimensional Lie algebra of characteristic distinct from 2 and from 3. Suppose that L contains an extremal element that is not a sandwich, that is, an eleme…
Exploring an ultracold Fermi-Fermi mixture: Interspecies Feshbach resonances and scattering properties of 6Li and 40K
E. Wille, F. M. Spiegelhalder, G. Kerner +10
We report on the observation of Feshbach resonances in an ultracold mixture of two fermionic species, 6Li and 40K. The experimental data are interpreted using a simple asymptotic b…
Left-invariant Stochastic Evolution Equations on SE(2) and its Applications to Contour Enhancement and Contour Completion via Invertible Orientation Scores
Remco Duits, Erik Franken
We provide the explicit solutions of linear, left-invariant, (convection)-diffusion equations and the corresponding resolvent equations on the 2D-Euclidean motion group SE(2). Thes…
High-bandwidth viscoelastic properties of aging colloidal glasses and gels
S. Jabbari-Farouji, M. Atakhorram, D. Mizuno +5
We report measurements of the frequency-dependent shear moduli of aging colloidal systems that evolve from a purely low-viscosity liquid to a predominantly elastic glass or gel. Us…
A mechanical experimental setup to simulate vocal folds vibrations. Preliminary results
Nicolas Ruty, Annemie Van Hirtum, Xavier Pelorson +2
This paper contributes to the understanding of vocal folds oscillation during phonation. In order to test theoretical models of phonation, a new experimental set-up using a deforma…
Weak convergence of measure-valued processes and -point functions
Mark Holmes, Edwin Perkins
We prove a sufficient set of conditions for a sequence of finite measures on the space of cadlag measure-valued paths to converge to the canonical measure of super-Brownian motion…
Total control over ultracold interactions via electric and magnetic fields
Bout Marcelis, Boudewijn Verhaar, Servaas Kokkelmans
The scattering length is commonly used to characterize the strength of ultracold atomic interactions, since it is the leading parameter in the low-energy expansion of the scatterin…
