On Coexistence Patterns - Hierarchies of Intricate Partially Symmetric Solutions to Stuart-Landau Oscillators with Nonlinear Global Coupling

This book is about coexistence patterns in ensembles of globally coupled nonlinear oscillators. Coexistence patterns in this respect are states of a dynamical system in which the dynamics in some parts of the system differ significantly from those in other parts, even though there is no underlying structural difference between the different parts. In other words, these asymmetric patterns emerge in a self-organized manner. 

As our main model, we use ensembles of various numbers of Stuart-Landau oscillators, all with the same natural frequency and all coupled equally strongly to each other. Employing computer simulations, bifurcation analysis and symmetry considerations, we uncover the mechanism behind a wide range of complex patterns found in these ensembles. Our starting point is the creation of so-called chimeras, which are subsequently treated within a new and broader context of related states.

Physics of Energy Conversion

Covers the physical basis of the most important energy conversion processes used for energy supply. The aim of thistextbook is to provide a unified view on the different energy converter systemsranging from thermal power plants to solar cells. The central theme is the treatment of energy converters as open thermo dynamicalsystems and the performance of efficiency analyses, based on the concept of exergy.

  • Presents the physics behind the most important energy converters in a unified framework.
  • Evaluatesthe performance of ideal and realistic energy converters in terms of energy and exergy efficiencies.
  • Provides basic concepts needed for a discussion of energy converters, such as chemical and applied thermodynamics, electrochemistry and solid state physics.

Authors: Prof. Dr. Katharina Krischer and Dipl. Phys. Konrad Schönleber.
