This introduction to the concepts and methods of quantum mechanics employs the analysis of one-dimensional problems to offer students a quantitative understanding of atomic, molecular, solid-state, and nuclear physics. Applications of these concepts and methods help answer the most intriguing questions of modern physics: What holds matter together? Holds it apart? How does the variety of chemical properties of different elements arise? How do electrons move through solids? Why do nuclei that occur in nature possess only certain combinations of protons and neutrons? The text presents meaningful problems by topic — supplemented by ample illustrations, applications, and exercises — that address the most intriguing questions of modern physics. Answers to selected problems appear in the appendix. Geared toward science and engineering majors, this volume is also appropriate for independent study by those who have completed a general physics course.

In der Quantentheorie werden Observable durch Operatoren im Hilbert-Raum dargestellt. Der dafür geeignete mathematische Rahmen sind die Cx - Algebren, welche Matrizen und komplexe Funktionen verallgemeinern. Allerdings benötigt man in der Physik auch unbeschränkte Operatoren, deren Problematik eigens untersucht werden muß. Dementsprechend werden zunächst mathematische Fragen studiert und dann die Methoden auf atomare Systeme angewandt. Obgleich man außer dem Wasserstoffatom kaum explizit lösbare Probleme findet, lassen sich nicht nur allgemeine qualitative Fragen, etwa bezüglich des Energiespektrums und Streuverhaltens, beantworten, sondern auch quantitativ kann man auch für kompliziertere Systeme für meßbare Größen Schranken teils befriedigender Genauigkeit finden. Inhaltsverzeichnis: Einleitung: Die Struktur der Quantentheorie; Größenordnungen atomarer Systeme.- Die mathematische Formulierung der Quantenmechanik: Lineare Räume; Algebren; Darstellungen im Hilbertraum; Einparametrige Gruppen; Unbeschränkte Operatoren und quadratische Formen.- Quantendynamik: Das Weyl-System; Der Drehimpuls; Die Zeitentwicklung; Der Limes t ; Störungstheorie; Stationäre Streutheorie.- Atomare Systeme: Das Wasserstoffatom; Das H-Atom in äußeren Feldern; Heliumartige Atome; Streuung am einfachen Atom; Komplexe Atome; Kernbewegung und einfache Moleküle.

The fall of the Berlin Wall in 1989 and globalization have forced national history to yield place to European and global history. In medieval studies, Michael Borgolte has taken up the new challenge as no other German historian, encouraging the development of transcultural research on the Middle Ages. This volume includes several of his essays, but is intended to serve more as the basis for further research rather than to take stock of his work.

The Standard Model has been the model of choice for nuclear structure since the late 1960s. However, 40 years later, scientists are still struggling to validate it. Nuclear Alternative offers an alternative explanation for the structure of matter that uses particles and forces observed and characterized since the 1930s. By redesigning the models of the proton, neutron, and electron, and developing a nuclear binding mechanism similar to covalent bonds in atoms, the book systematically develops models for more than 250 stable nuclei. It then uses the models to explain alpha and beta decay, and nuclear fission and fusion.

Common to all matter and its smallest and most fundamental unit, the atom determines the properties of a substance and how it responds to other materials and stimuli. Dividing the atom further reveals several smaller particles whose activity forms the heart of nuclear physics. Readers will discover the structure of the atom as well as the ways in which its electrons, protons, and neutrons facilitate both radioactivity and nuclear reactions, both of which have been crucial to technological advancements since the 20th century.

Thermal Processes Using Attosecond Laser Pulses

When Time Matters

This book is based on the results of our interest in the ?eld of ultrashort laser pulses interaction with matter. The aim of our monograph was to build the balanced description of the thermal transport phenomena generated by laser pulses shorter than the characteristic relaxation time. In the book we explore the matter on the quark, nuclear as well atomic scales. Also on the cosmic scale (Planck Era) the thermal disturbance shorter than the Planck time creates the new picture of the Universe. The mathematics, especially PDE, are the main tool in the description of the ultrashort thermal phenomena. Two types of the PDE: parabolic and hyperbolic partial di?erential equations are of special interest in the study of the thermal processes. We assume a moderate knowledge of basic Fourier and d’Alembert eq- tions. The scope of the book is deliberately limited to the background of the quantum mechanics equations: Schr ̈ odinger and Klein-Gordon. In this book the attosecond laser pulses are the main source of the dist- bance of the thermal state of the matter. Recently, the attosecond laser pulses constitute a novel tool for probing processes taking place on the time scale of electron motion inside atoms. The research presented in this book appears to provide the basic tools and concepts for attosecond thermal dynamics. Nevertheless much research is still needed to make this emerging ?eld routinely applicable for a broad range of processes on atomic and subatomic scales.

The Search for the Meaning of Space, Time, and Matter

The book gives a comprehensive introduction for interested general readers, into the development and structure of concepts, ideas and theory formation about the elementary building blocks of matter, the forces with which these particles interact and about the fundamental nature of space itself. Einsteins theory of the cosmos and the recent discovery of the presence of a dark energy which leads to an accelerated expansion of cosmic space, provide the background for the most astonishing recent developments in the search for the origin of space and matter. The String-Theory revolution has led to the notion that nature may not follow one unique set of laws to build worlds, but that innumerable many possible universes may exist, that worlds may be emerging and disappearing like biological species and that our existence may be extraordinarily rare and therefore precious. An introduction to the concept of emergence in self-organizing systems is given to make the connection to the idea that Emergence may be the inherent creative property of space and matter at the quantum level.

From the Introduction: Nanotechnology and its underpinning sciences are progressing with unprecedented rapidity. With technical advances in a variety of nanoscale fabrication and manipulation technologies, the whole topical area is maturing into a vibrant field that is generating new scientific research and a burgeoning range of commercial applications, with an annual market already at the trillion dollar threshold. The means of fabricating and controlling matter on the nanoscale afford striking and unprecedented opportunities to exploit a variety of exotic phenomena such as quantum, nanophotonic and nanoelectromechanical effects. Moreover, researchers are elucidating new perspectives on the electronic and optical properties of matter because of the way that nanoscale materials bridge the disparate theories describing molecules and bulk matter. Surface phenomena also gain a greatly increased significance; even the well-known link between chemical reactivity and surface-to-volume ratio becomes a major determinant of physical properties, when it operates over nanoscale dimensions. Against this background, this comprehensive work is designed to address the need for a dynamic, authoritative and readily accessible source of information, capturing the full breadth of the subject. Its six volumes, covering a broad spectrum of disciplines including material sciences, chemistry, physics and life sciences, have been written and edited by an outstanding team of international experts. Addressing an extensive, cross-disciplinary audience, each chapter aims to cover key developments in a scholarly, readable and critical style, providing an indispensible first point of entry to the literature for scientists and technologists from interdisciplinary fields. The work focuses on the major classes of nanomaterials in terms of their synthesis, structure and applications, reviewing nanomaterials and their respective technologies in well-structured and comprehensive articles with extensive cross-references. It has been a constant surprise and delight to have found, amongst the rapidly escalating number who work in nanoscience and technology, so many highly esteemed authors willing to contribute. Sharing our anticipation of a major addition to the literature, they have also captured the excitement of the field itself in each carefully crafted chapter. Along with our painstaking and meticulous volume editors, full credit for the success of this enterprise must go to these individuals, together with our thanks for (largely) adhering to the given deadlines. Lastly, we record our sincere thanks and appreciation for the skills and professionalism of the numerous Elsevier staff who have been involved in this project, notably Fiona Geraghty, Megan Palmer and Greg Harris, and especially Donna De Weerd-Wilson who has steered it through from its inception. We have greatly enjoyed working with them all, as we have with each other.

Sind Sie zufrieden mit Ihrem Leben, so wie es ist? Oder sagen Sie: Soll’s das wirklich schon gewesen sein? Wenn Sie sich insgeheim denken, dass irgendwo Größeres auf Sie wartet, Ihnen aber noch der letzte Anstoß fehlt, um endlich die verdammte Komfortzone zu verlassen, dann sind Sie hier genau richtig. Denn Jen Sincero wird Sie packen und von der Couch ziehen, damit Sie endlich das Leben leben, auf das Sie selbst neidisch wären. Aber Vorsicht: Nach diesem Buch ist das Leben definitiv anders! Jen Sinceros eigenes Leben war lange Zeit alles andere als berauschend: Sie hangelte sich von einem schlechten Job zum nächsten, hatte nie genug Geld und fuhr ein Auto, das fast auseinanderfiel. Bis sie entschied, dass sie etwas ändern muss. Sie las gefühlt jedes Selbsthilfebuch auf dieser Welt und ging zu Seminaren, bei denen man Leute umarmen oder seine Wut an einem Kissen auslassen musste. Und – es half. Jen Sincero schrieb ihr erstes Buch und schließlich noch ein zweites, das zu einem Bestseller wurde. Sie arbeitete als Coach, gab Seminare, reiste um die Welt und sprach vor großem Publikum. Sie erreichte genau das, wovon sie immer geträumt hatte. Jetzt gibt Jen Sincero ihre Erkenntnisse und ihr Wissen weiter und zeigt, wie man die Fähigkeiten, die in einem schlummern, endlich zum Blühen bringt. Es geht darum, sich glasklar darüber zu werden, was einen glücklich macht und wobei man sich am lebendigsten fühlt, und es dann mutig umzusetzen, statt sich einzureden, man könnte es nicht schaffen. Mit viel Humor und Schlagfertigkeit gibt sie praktische Ratschläge und zeigt Übungen, die dabei helfen die Selbstsabotage zu beenden und das zu erreichen, wovon man träumt.

Characterization of Nanostructures

The techniques and methods that can be applied to materials characterization on the microscale are numerous and well-established. Divided into two parts, Characterization of Nanostructures provides thumbnail sketches of the most widely used techniques and methods that apply to nanostructures, and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. Section I: Techniques and Methods overviews the physical principles of the main techniques and describes those operational modes that are most relevant to nanoscale characterization. It provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The section covers both mainstream and less commonly used techniques. Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deals with the methods for materials characterization of generic types of systems, using carefully chosen illustrations from the literature. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterization. The volume concludes with a series of flow charts and brief descriptions of tactical issues. The authors focus on the needs of the research laboratory but also address those of quality control, industrial troubleshooting, and online analysis. Characterization of Nanostructures describes those techniques and their operational modes that are most relevant to nanoscale characterization. It is especially relevant to systems of different dimensionalities and functionalities. The book builds a bridge between generalists, who play vital roles in the post-disciplinary area of nanotechnology, and specialists, who view themselves as more in the context of the discipline.
