Polarized 3He as a probe for short-range spin-dependent interactions
A. K. Petukhov, G. Pignol, D. Jullien +1
We have studied the relaxation of a spin-polarized gas in a magnetic field, in the presence of short-range spin-dependent interactions. As a main result we have established a link…
Hierarchical Markovian modeling of multi-time scale systems
M. Abel, K. H. Andersen, G. Lacorata
We present a systematic way to analyze and model systems having many characteristic time-scales. The method we propose is employed for a test-case of a meandering jet model manifes…
The Stability Balloon for Two-dimensional Vortex Ripple Patterns
J. L. Hansen, M. van Hecke, C. Ellegaard +4
Patterns of vortex ripples form when a sand bed is subjected to an oscillatory fluid flow. Here we describe experiments on the response of regular vortex ripple patterns to sudden…
A Particle Model of Rolling Grain Ripples Under Waves
K. H. Andersen
A simple model is presented for the formation of rolling grain ripples on a flat sand bed by the oscillatory flow generated by a surface wave. An equation of motion is derived for…
Bursts and Shocks in a Continuum Shell Model
K. H. Andersen, T. Bohr, M. H. Jensen +1
We study a "burst" event, i. e. the evolution of an initial condition having support only in a finite interval of k-space, in the continuum shell model due to Parisi. We show that…
