Pulsar timing is a promising method for detecting gravitational waves in the nano-Hertz band. In his prize winning Ph.D. thesis Rutger van Haasteren deals with how one takes thousands of seemingly random timing residuals which are measured by pulsar observers, and extracts information about the presence and character of the gravitational waves in the nano-Hertz band that are washing over our Galaxy. The author presents a sophisticated mathematical algorithm that deals with this issue. His algorithm is probably the most well-developed of those that are currently in use in the Pulsar Timing...

In this thesis, novel Monte Carlo methods for precisely calculating the critical phenomena of the effectively frustrated quantum spin system are developed and applied to the critical phenomena of the spin-Peierls systems. Three significant methods are introduced for the first time: a new optimization algorithm of the Markov chain transition kernel based on the geometric weight-allocation approach, the extension of the worm (directed-loop) algorithm to nonconserved particles, and the combination with the level spectroscopy. Utilizing these methods, the phase diagram of the one-dimensional XXZ...

In biological systems, molecules hierarchically form ordered assemblies and macroscopic substances, as exemplified by the assembly of proteins. The development of such systems using oligomeric macromolecules obtained by organic synthesis can provide insights into biological phenomena and will lead to the creation of new materials. In this regard, synthetic double helix molecules are attractive subjects of study because they have an important structural motif that appears widely in nature and can exhibit dynamic structural change. This thesis describes an unprecedented bottom-up approach using...

"Catalytic Microreactors for Portable Power Generation" addresses a problem of high relevance and increased complexity in energy technology. This thesis outlines an investigation into catalytic and gas-phase combustion characteristics in channel-flow, platinum-coated microreactors. The emphasis of the study is on microreactor/microturbine concepts for portable power generation and the fuels of interest are methane and propane. The author carefully describes numerical and experimental techniques, providing a new insight into the complex interactions between chemical kinetics and molecular...

The development and application of bioactive nano-structured constructs for tissue regeneration is the focus of the research summarised in this thesis. Moreover, a particular focus is the rational use of supercritical carbon dioxide foaming and electrospinning technologies which can lead to innovative polymeric bioresorbable scaffolds made of hydrolysable (both commercial and 'ad-hoc' synthesized) polyesters. Mainly, the author discusses the manipulation of polymer chemical structure and composition to tune scaffold physical properties, and optimization of scaffold 3D architecture by a smart...

Large mass bolometers are used in particle physics experiments to search for rare processes, like neutrinoless double beta decay and dark matter interactions. In the next years the CUORE experiment (a 1 Ton detector composed by 1000 crystals of TeO2 operated as bolometers in a large cryostat at 10mK) will be the particle physics experiment with the highest chance of discovering the Majorana neutrino, a long standing and yet fundamental question of particle physics. The study presented in this book was performed on the bolometers of the CUORE experiment. The response function of...

This thesis covers the few-cycle laser-driven acceleration of electrons in a laser-generated plasma. This so-called laser wakefield acceleration (LWFA) relies on strongly driven plasma waves for the generation of accelerating gradients in the range of several 100 GV/m, a value four orders of magnitude larger than that attainable by conventional accelerators. This thesis demonstrates that laser pulses with an ultrashort duration of 8 fs and a peak power of 6 TW allow the production of electron energies up to 50 MeV via LWFA. The special properties of laser accelerated electron pulses, namely...

This work addresses time-delay in complex nonlinear systems and, in particular, its applications in complex networks; its role in control theory and nonlinear optics are also investigated. Delays arise naturally in networks of coupled systems due to finite signal propagation speeds and are thus a key issue in many areas of physics, biology, medicine, and technology. Synchronization phenomena in these networks play an important role, e.g., in the context of learning, cognitive and pathological states in the brain, for secure communication with chaotic lasers or for gene regulation. The thesis...

This book shows how transiting planets may be used to infer the presence of exomoons through deviations in time and duration of planetary eclipses. It shows that habitable-zone exomoons above 0.2 Earth-masses can be detected with the Kepler space telescope.
