A causal continuous-time stochastic model for the turbulent energy cascade in a helium jet flow
Emil Hedevang, Jürgen Schmiegel
We discuss continuous cascade models and their potential for modelling the energy dissipation in a turbulent flow. Continuous cascade processes, expressed in terms of stochastic in…
Assessing Relative Volatility/Intermittency/Energy Dissipation
Ole E. Barndorff-Nielsen, Mikko S. Pakkanen, Jürgen Schmiegel
We introduce the notion of relative volatility/intermittency and demonstrate how relative volatility statistics can be used to estimate consistently the temporal variation of volat…
Determining source cumulants in femtoscopy with Gram-Charlier and Edgeworth series
Hans C Eggers, Michiel B de Kock, Jurgen Schmiegel
Lowest-order cumulants provide important information on the shape of the emission source in femtoscopy. For the simple case of noninteracting identical particles, we show how the f…
Lévy-based growth models
Kristjana Ýr Jónsdóttir, Jürgen Schmiegel, Eva B. Vedel Jensen
In the present paper, we give a condensed review, for the nonspecialist reader, of a new modelling framework for spatio-temporal processes, based on Lévy theory. We show the potent…
Data-driven derivation of the turbulent energy cascade generator
J. Cleve, T. Dziekan, J. Schmiegel +4
Within the framework of random multiplicative energy cascade models of fully developed turbulence, expressions for two-point correlators and cumulants are derived, taking into acco…
Artificiality of multifractal phase transitions
Martin Wolf, Jürgen Schmiegel, Martin Greiner
A multifractal phase transition is associated to a nonanalyticity in the generalised dimensions. We show that its occurrence is an artifact of the asymptotic scaling behaviour of i…
