Propagating wave correlations in complex systems
Stephen C Creagh, Gabriele Gradoni, Timo Hartmann +1
We describe a novel approach for computing wave correlation functions inside finite spatial domains driven by complex and statistical sources. By exploiting semiclassical approxima…
A Phase-Space Approach for Propagating Field-Field Correlation Functions
Gabriele Gradoni, Stephen Creagh, Gregor Tanner +2
We show that radiation from complex and inherently random but correlated wave sources can be modelled efficiently by using an approach based on the Wigner distribution function. Ou…
A boundary integral formalism for stochastic ray tracing in billiards
David J. Chappell, Gregor Tanner
Determining the flow of rays or particles driven by a force or velocity field is fundamental to modelling many physical processes, including weather forecasting and the simulation…
A sub-determinant approach for pseudo-orbit expansions of spectral determinants in quantum maps and quantum graphs
Daniel Waltner, Sven Gnutzmann, Gregor Tanner +1
We study implications of unitarity for pseudo-orbit expansions of the spectral determinants of quantum maps and quantum graphs. In particular, we advocate to group pseudo-orbits in…
A hybrid approach for predicting the distribution of vibro-acoustic energy in complex built-up structures
Dmitrii N Maksimov, Gregor Tanner
Finding the distribution of vibro-acoustic energy in complex built-up structures in the mid-to-high frequency regime is a difficult task. In particular, structures with large varia…
Dynamical Energy Analysis - determining wave energy distributions in complex vibro-acoustical structures
Gregor Tanner
We propose a new approach towards determining the distribution of mechanical and acoustic wave energy in complex built-up structures. The technique interpolates between standard St…
