Shattered Symmetry
Symmetry is at the heart of our understanding of matter. This book tells the fascinating story of the constituents of matter from a common symmetry perspective. The standard model of elementary particles and the periodic table of chemical elements have the common goal to bring order in the bewildering chaos of the constituents of matter. Their success relies on the presence of fundamental symmetries in their core. The purpose of Shattered Symmetry is to share the admiration for the power and the beauty of these symmetries. The reader is taken on a journey from the basic geometric symmetry group of a circle to the sublime dynamic symmetries that govern the motions of the particles. Along the ...
The Theory of the Jahn-Teller Effect
This book provides a comprehensive discussion of the Jahn-Teller Effect (JTE), focusing on the boson-fermion interaction. While current research is concerned with measuring and calculating ever more sophisticated and complex manifestations of the JT effect, the present volume takes away the epicycles of the theory and focuses on the symmetry dilemma at its core. When fermions and bosons meet, they get entangled and form a new dynamic reality. According to the rules of Molecular Symmetry, this reality is limited to a small set of patterns, with degeneracy cardinalities: 2, 3, 4, 5, and 6. The novelty of the book is that it adopts a unique mathematical technique, known as the Bargmann-Fock representation, and treats all degeneracies in detail. So far, this method was only applied to the simplest doublet case therefore its extension to the entire range of cases offers a new unified perspective. This volume will help the reader acquire a clear understanding of the JT effect, discover its universal mechanism and it will be a great tool for researchers and graduates working on this topic.
Nanostructures
Novel carbon allotropes, such as spherical fullerenes and nanotubes, have been added, in the last three decades, to the traditionally recognised diamond and graphite. Although fullerene C60 has been speculated about for a long time. A fullerene is, according to a classical definition, an all-carbon molecule consisting entirely of pentagons (exactly 12) and hexagons (n/2-10). Non-classical fullerene extensions to include rings of other sizes have been considered. Fullerenes are commonly synthesised by arc-discharge or laser ablation methods. Spherical fullerenes became nowadays parts of real chemistry: they can be functionalised or inserted in supramolecular assemblies.

An edited volume featuring chapters on multidisciplinary aspects of the Periodic Table, particularly focusing on the history and philosophy of chemistry
Foundations Of Quantum Mechanics In The Light Of New Technology: Isqm-tokyo '05 - Proceedings Of The 8th International Symposium
The goal of the 8th International Symposium on Foundations of Quantum Mechanics in the Light of New Technology was to link recent advances in technology with fundamental problems and issues in quantum mechanics with an emphasis on quantum coherence, decoherence, and geometrical phase.The papers collected in this volume cover a wide range of quantum physics, including quantum information and entanglement, quantum computing, quantum-dot systems, the anomalous Hall effect and the spin-Hall effect, spin related phenomena, superconductivity in nano-systems, precise measurements, and fundamental problems. The volume serves both as an excellent reference for experts and a useful introduction for newcomers to the field of quantum coherence and decoherence.
Vibronic Interactions and the Jahn-Teller Effect
The concepts of the Jahn-Teller effect and vibronic coupling are being applied to more and more systems in both chemistry and physics. Aspects of structural chemistry such as the distortion of the nuclear framework to a lower-symmetry conformation have received an increasing attention, as well as the dynamics on the coupled potential energy surfaces. The Jahn-Teller intersections are now recognized as prototype cases of conical intersections where the nuclear motion is known to be inherently nonadiabatic in nature and interchanges freely between the different potential energy surfaces. In the condensed phase especially, the significance of the Jahn-Teller effect has been increasingly appreci...
Applying Molecular and Materials Modeling
Computational molecular and materials modeling has emerged to deliver solid technological impacts in the chemical, pharmaceutical, and materials industries. It is not the all-predictive science fiction that discouraged early adopters in the 1980s. Rather, it is proving a valuable aid to designing and developing new products and processes. People create, not computers, and these tools give them qualitative relations and quantitative properties that they need to make creative decisions. With detailed analysis and examples from around the world, Applying Molecular and Materials Modeling describes the science, applications, and infrastructures that have proven successful. Computational quantum chemistry, molecular simulations, informatics, desktop graphics, and high-performance computing all play important roles. At the same time, the best technology requires the right practitioners, the right organizational structures, and - most of all - a clearly understood blend of imagination and realism that propels technological advances. This book is itself a powerful tool to help scientists, engineers, and managers understand and take advantage of these advances.
Electron-phonon Dynamics And Jahn-teller Effect - Proceedings Of The Xiv International Symposium
The Jahn-Teller effect is a consequence of the electron-phonon coupling in high symmetry systems. Its influence covers a wide range of physical and chemical properties and systems. As the biannual Jahn-Teller symposia bring together experimental and theoretical physicists and chemists from all over the world, this proceedings volume reports the latest scientific news on the effect.The contents of the volume range from the general aspects to some special topics, such as ultrafast processes, fullerenes, point defects, cooperative phenomena, HTSC and oxide properties. Some contributions are dedicated to the memory of Mary O'Brien, a globally honored specialist in the theory of the Jahn-Teller effect. Throughout personal reminiscences of O'Brien's enormous contributions to the subject, the recent history of the effect is summarized.
Intermolecular Forces
The study of intermolecular forces began over one hundred years ago in 1873 with the famous thesis of van der Waals. In recent decades, knowledge of this field has expanded due to intensive research into both its theoretical and the experimental aspects. This is particularly true for the type of very strong cohesive force stressed in 1920 by Latimer and Rodebush: the hydrogen bond, a phenomenon already outlined in 1912 by Moore and Winemill. Hydrogen bonds exert a profound influence on most of the physical and chemical properties of the materials in which they are formed. Not only do they govern viscosity and electrical conductivity, they also intervene in the chemical reaction path which de...
Philosophy as Descartes Found It
What was philosophy as Descartes found it around 1620? What was philosophy like before Descartes reformed it after 1637? What features of philosophy did he want to fix, and what tools did he use? To answer such questions, how should philosophers do their work today? One answer is surprising: that Descartes wrote picture books, for example. Another is challenging: that philosophers in the present would be better students of their discipline's past if they spent less time on past philosophy as they commonly understand it. The change would be transformative. But big changes have happened in philosophy's past for non-philosophical reasons that need attention from philosophers today, when oblivio...
