Atomicity through Fractal Measure Theory: Mathematical and Physical Fundamentals with Applications

by Alina Gavriluţ Ioan Mercheş Maricel Agop

This book presents an exhaustive study of atomicity from a mathematics perspective in the framework of multi-valued non-additive measure theory. Applications to quantum physics and, more generally, to the fractal theory of the motion, are highlighted. The study details the atomicity problem through key concepts, such as the atom/pseudoatom, atomic/nonatomic measures, and different types of non-additive set-valued multifunctions. Additionally, applications of these concepts are brought to light in the study of the dynamics of complex systems.The first chapter prepares the basics for the next chapters. In the last chapter, applications of atomicity in quantum physics are developed and new concepts, such as the fractal atom are introduced. The mathematical perspective is presented first and the discussion moves on to connect measure theory and quantum physics through quantum measure theory. New avenues of research, such as fractal/multifractal measure theory with potential applications in life sciences, are opened.

Atomistic Spin Dynamics: Foundations and Applications

by Olle Eriksson Anders Bergman Lars Bergqvist Johan Hellsvik

The purpose of this book is to provide a theoretical foundation and an understanding of atomistic spin-dynamics (ASD), and to give examples of where the atomistic Landau-Lifshitz-Gilbert equation can and should be used. As argued in the text, a description of magnetism in an atomistic way is very natural and allows for an interpretation of experimental results in a clear and deep way. This description also allows for calculations, from first principles, of all parameters needed to perform the spin-dynamics simulations, without using experimental results as input to the simulations. As shown in the book, we are now at a very exciting situation, where it is possible to perform accurate and efficient atomistic simulations on a length- and time-scale which is balancing on the edge of what is experimentally possible. In this way, ASD simulations can both validate and be validated by state-of-the art experiments, and ASD simulations also have the possibility to act as a predictive tool that is able to explain the magnetization dynamics in experimentally inaccessible situations. The purpose of this book has been to communicate technically relevant concepts. An even larger motivation is to communicate an inspiration to magnetism and magnetization dynamics, and the emerging technological fields that one may foresee, e.g. in magnonics, solitonics and skyrmionics.

Atomistics of Fracture (Nato Conference Series #5)

by R. M. Latanison J. R. Pickens

It is now more than 100 years since certain detrimental effects on the ductility of iron were first associated with the presence of hydrogen. Not only is hydrogen embrittlement still a major industri­ al problem, but it is safe to say that in a mechanistic sense we still do not know what hydrogen (but not nitrogen or oxygen, for example) does on an atomic scale to induce this degradation. The same applies to other examples of environmentally-induced fracture: what is it about the ubiquitous chloride ion that induces premature catastrophic fracture (stress corrosion cracking) of ordinarily ductile austenitic stainless steels? Why, moreover, are halide ions troublesome but the nitrate or sulfate anions not deleterious to such stainless steels? Likewise, why are some solid metals embrit­ tled catastrophically by same liquid metals (liquid metal embrit­ tlement) - copper and aluminum, for example, are embrittled by liquid mercury. In short, despite all that we may know about the materials science and mechanics of fracture on a macroscopic scale, we know little about the atomistics of fracture in the absence of environmental interactions and even less when embrittlement phe­ nomena such as those described above are involved. On the other hand, it is interesting to note that physical chemists and surface chemists also have interests in the same kinds of interactions that occur on an atomic scale when metals such as nickel or platinum are used, for example, as catalysts for chemical reactions.

Atomkraft: Eine Einführung in die Probleme des Atomzeitalters (Verständliche Wissenschaft #73)

by Niels Arley Helge Skov

Dem nach der Tschernobyl-Katastrophe stark angewachsenen Informationsbedürfnis über die Möglichkeiten und Risiken der Kernkraft-Ausnutzung trägt diese Neuauflage Rechnung. In verständlicher Form wird in die technischen, militärischen, medizinischen und biologischen Probleme des Atomzeitalters eingeführt. Besondere Beachtung findet dabei das Dilemma der modernen Technik, häufig mit der Lösung alter Probleme neue zu kreieren.

Atomkraft: Eine Studie über die technischen und wirtschaftlichen Aussichten von Atomkraftwerken

by Friedrich Münzinger

Diese Studie ist wahrscheinlich das erste Buch, das versucht, die zahlreichen bisher vorgeschlagenen Bauarten von Reaktoren (Atom­ meilern) systematisch zu ordnen und auf ihre Eignung für Elektrizitäts­ werke in technischer und wirtschaftlicher Beziehung kritisch zu prüfen. Ein eigenartiger Zufall will es, daß ich vor 35 Jahren über eine andere gleichfalls in Amerika entwickelte Neuerung, nämlich Kohlenstaub­ feuerungen für ortsfeste Dampfkessel, auch das erste Buch heraus­ gebracht habe. Mein ursprüngliches Bedenken, vorliegende Abhandlung zu schreiben, weil Deutschland bisher an der Entwicklung von Reaktoren nicht mit­ arbeiten konnte, wurde schließlich durch die Überlegung überwunden, daß es für die große Zahl derer, denen die ausländische Fachliteratur nicht zur Verfügung steht, zur Zeit sehr schwer ist, sich ein einiger­ maßen klares Bild vom Stand der Dinge zu machen. Die in deut­ schen Zeitschriften erschienenen, über ausländische Erfahrungen be­ richtenden Veröffentlichungen beschränken sich nämlich - ähnlich wie manche der betreffenden Originalarbeiten - im allgemeinen auf reine Beschreibung einzelner Reaktoren, wodurch man nur schwer erkennen kann, was wichtig ist und was nicht. Dieser Mißstand dürfte sich noch verstärken, weil infolge der Lockerung der Geheimhaltungsvorschriften die Zahl der einschlägigen amerikanischen Veröffentlichungen in den letzten Monaten stark angewachsen ist. Vorliegende Abhandlung möchte daher als eine Art Führer auf diesem neuartigen Gebiete der Technik dienen und das Vertrautwerden mit der verwickelten Materie erleich­ tern, damit Deutschland den großen Vorsprung des Auslandes schnell aufholen kann.

Atommüll - die teure Erbschaft: Von der Kernenergiegewinnung zur Endlagersuche (essentials)

by Klaus Stierstadt

Bei der Energiegewinnung aus Atomkernen entstehen radioaktive Abfälle. Deren radioaktive Strahlung ist für belebte Materie außerordentlich schädlich. Solche Strahlenschäden werden besprochen und mit der natürlichen Strahlenbelastung verglichen. Der Atommüll muss sorgfältig entsorgt werden, was bis heute kaum geschieht. Die Möglichkeiten und Probleme einer sicheren Endlagerung werden diskutiert.

Atomphysik: Eine Einführung

by Theo Mayer-Kuckuk

Der Inhalt dieses Buches entspricht in seinem Umfang ungefähr einer einsemestrigen Einführungsvorlesung in die Atomphysik. Vorausgesetzt werden einige Kenntnisse aus der Mechanik und Elektrodynamik sowie Grundkenntnisse in Vektor-und Differential­ rechnung. Vertrautheit mit der Quantenmechanik wird nicht unbedingt vorausgesetzt. Natürlich ist sie nützlich, und der Leser wird dann einiges überschlagen können. Aber der vor­ liegende Text ist vor allem auch für Studenten gedacht, die etwa gleichzeitig mit dem Studium der Atomphysik und der Quantenmechanik beginnen, oder die sich auf die Quantenmechanik erst vorbereiten wollen. Schließlich hat sich die Quantenmechanik historisch an der Atomphysik entwickelt und ist auch in der Darstellung nicht gut von ihr zu trennen. Daher werden in dem vorliegenden Text, ausgehend von den experimen­ tellen Grundlagen, zunächst die einfachsten quantenmechanischen Begriffe erläutert. Es wird dann im weiteren hauptsächlich von der Schrödingergleichung und von einfachen Symmetrie-Betrachtungen Gebrauch gemacht. Diese Darlegungen können und sollen ein reguläres Studium der Quantenmechanik natürlich nicht ersetzen_ Sie sollen aber eine gewisse Ergänzung dadurch bieten, daß die Perspektiven anders liegen als bei einer theo­ retischen Einführung in die Quantenmechanik. Diese Wiederholung beim Lernen schadet nicht, im Gegenteil: alle Erfahrung zeigt, daß kaum jemand in der Lage ist, Quanten­ mechanik auf Anhieb zu lernen und damit umzugehen. Das Verständnis der Quanten­ mechanik entsteht vielmehr normalerweise durch längere Gewöhnung und durch ein vielfaches Durchdenken der Probleme aus verschiedenen Blickrichtungen.

Atomphysik für Höhlenmenschen und andere Anfänger: Das Universum von innen: Moleküle, Atome und Elementarteilchen (essentials)

by Jürgen Beetz

Jürgen Beetz zeigt zuerst den Ursprung der erdachten Geschichten der Physik aus der Steinzeit, denn vieles ist so einfach, dass es schon Steinzeitmenschen hätten verstehen können. Im Anschluss daran erklärt der Autor den Aufbau von Atomen und sagt etwas zu ihren physikalischen Größen aus. Obwohl „Atom“ eigentlich „unteilbar“ bedeutet, bestehen Atome dennoch aus Teilen – dies erläutert er im Weiteren genau. Schließlich bespricht er die geheimnisvollen „Quanten“ und ihr merkwürdiges Verhalten.

Atoms and Alchemy: Chymistry and the Experimental Origins of the Scientific Revolution

by William R. Newman

Since the Enlightenment, alchemy has been viewed as a sort of antiscience, disparaged by many historians as a form of lunacy that impeded the development of rational chemistry. But in Atoms and Alchemy, William R. Newman—a historian widely credited for reviving recent interest in alchemy—exposes the speciousness of these views and challenges widely held beliefs about the origins of the Scientific Revolution. Tracing the alchemical roots of Robert Boyle’s famous mechanical philosophy, Newman shows that alchemy contributed to the mechanization of nature, a movement that lay at the very heart of scientific discovery. Boyle and his predecessors—figures like the mysterious medieval Geber or the Lutheran professor Daniel Sennert—provided convincing experimental proof that matter is made up of enduring particles at the microlevel. At the same time, Newman argues that alchemists created the operational criterion of an “atomic” element as the last point of analysis, thereby contributing a key feature to the development of later chemistry. Atomsand Alchemy thus provokes a refreshing debate about the origins of modern science and will be welcomed—and deliberated—by all who are interested in the development of scientific theory and practice.
