The classical approach for studying atmospheric variability is based on defining a
background state and studying the linear stability of the small fluctuations around such a …

The scaling behavior of the excited energy states of the directed polymer in random media is
analyzed numerically. We find that the spatial correlations of polymer energies scale as∼ k …

The scaling behavior of the excited energy levels of the directed polymer in random media is
analyzed numerically. We find that the spatial correlations of polymer energies scale as …

A review of the results obtained for hard disk fluids confined to a quasi-one-dimensional
(QOD) system is presented. One of the main achievements in recent years has been …

The covariant Lyapunov analysis is generalized to systems attached to deterministic thermal
reservoirs that create a heat current across the system and perturb it away from equilibrium …

This work reviews the authors' contributions to the Lyapunov analysis of extended dynamical
systems. Hydrodynamic Lyapunov modes (HLMs), the special Lyapunov vectors (LVs) …

First and foremost I would like to take the opportunity to thank my promotors doctor Andrew
Hallam and Professor Jutho Haegeman for the advice and guidance offered throughout the …
