The 1995 observation of Bose–Einstein condensation in dilute atomic vapours spawned the field of ultracold, degenerate quantum gases. Unprecedented developments in experimental design and precision control have led to quantum gases becoming the preferred playground for designer quantum many-body systems. This self-contained volume provides a broad overview of the principal theoretical techniques applied to non-equilibrium and finite temperature quantum gases. Covering Bose–Einstein condensates, degenerate Fermi gases, and the more recently realised exciton–polariton condensates, it fills a gap by linking between different methods with origins in condensed matter physics, quantum field theory, quantum optics, atomic physics, and statistical mechanics. Thematically organised chapters on different methodologies, contributed by key researchers using a unified notation, provide the first integrated view of the relative merits of individual approaches, aided by pertinent introductory chapters and the guidance of editorial notes. Both graduate students and established researchers wishing to understand the state of the art will greatly benefit from this comprehensive and up-to-date review of non-equilibrium and finite temperature techniques in the exciting and expanding field of quantum gases and liquids.

The revolution in twentieth century physics has changed the way we think about space, time and matter and our own place in the universe. It has offered answers to many of the big questions of existence, such as the ultimate nature of things and the how the universe came into being. It has undermined our belief in a Newtonian mechanistic universe and a deterministic future, posing questions about parallel universes, time-travel and the origin and end of everything. At the same time we have witnessed amazing attempts at unification so that physicists are able to contemplate the discovery of a single 'theory of everything' from which we could derive the masses and types of all particles and their interactions. This book tells the story of these discoveries and the people who made them, largely through the work of Nobel Prize winning physicists.

Die Grundlagen der Quantenmechanik

Mehrere Gründe bewogen mich, den Plan zu einem Buch über Quantenmechanik zu entwerfen, obwohl es in der Literatur schon manche Darstellung dieses Gebietes gibt. Einmal traf man bei den Lernenden immer wieder auf die Auf fassung, daß die Quantentheorie nur ein Provisorium der theoretischen Physik sei, aber zumindest noch einer genaueren Begründung bedürfe, da sowohl der mathematische Formalismus nicht exakt fundiert sei als auch die physikalische Interpretion sehr "nach Gefühl" in jedem Einzelfall durchgeführt würde. Nachdem das Buch von J. v. NEu MANN, Mathematische Grundlagen der Quantenmechanik, vergriffen war, konnte man kaum ein entsprechendes Werk empfehlen, das im physikalischen Zusammenhang die mathematischen Grundlagen klar legt. In dem vorliegenden Buche ist die eigentiiche Quantenmechamk (also ohne Feldtheorie) in der Weise dargestellt, daß man sie als em mathematisch wohlbegründetes und in sich genauso widerspruchs freies und abgeschlossenes System erkennt, wie die klassische Punkt mechanik. So wie die Kräfte, d. h. so wie die HAMILTON-Funktwn, in der klassischen Mechanik gegeben sein müssen, so m der Quanten mechanik der HAMILTON-Üperator. Die Herleitung eines Ansatzes für den HAMILTON-Operator eines Problems aus anderen Gebieten der Physik wird deshalb hier nicht näher begründet. Neben dem Wunsch, die Quantenmechamk als ein in sich geschlos senes Gebiet darzustellen, bestand ein zweiter Grund für die Abfassung des Buches in der inneren Harmonie zwischen mathematischer und physikalischer Struktur. Je größer die abstrakte Schönheit einer Theo rie, desto größer auch ihr Wahrheitsgehalt. Die innere Harmonie m der Struktur der Materie zu erkennen, d. h.

Das Buch behandelt drei physikalische Phänomene: die Bose-Einstein-Kondensation, Suprafluidität und Supraleitung. In seinem Aufbau verfolgt es das Ziel, die wesentlichen Konzepte und notwendigen mathematischen Formalismen zu motivieren. Das Buch beginnt mit dem einfachsten der drei Phänomene, der Bose-Einstein-Kondensation. Nach einem Überblick über grundlegenden Eigenschaften idealer Bose-Gase werden Verfahren zum Einfangen und Kühlen von Atomen vorgestellt, um schließlich auf die Realisierung von Bose-Einstein-Kondensaten in verdünnten atomaren Gasen eingehen zu können. Aufgrund von Zusammenfassungen und weiterführenden Literaturangaben ist das Werk gleichermaßen zum Selbststudium geeignet wie zur vertiefenden Vorlesungsbegleitung. Zahlreiche Übungsaufgaben, teils mit Lösungen und Hinweisen, ermöglichen die unmittelbare Überprüfung des Gelernten.

In the past decade, there has been a burst of new and fascinating physics associated to the unique properties of two-dimensional exciton polaritons, their recent demonstration of condensation under non-equilibrium conditions and all the related quantum phenomena, which have stimulated extensive research work. This monograph summarizes the current state of the art of research on exciton polaritons in microcavities: their interactions, fast dynamics, spin-dependent phenomena, temporal and spatial coherence, condensation under non-equilibrium conditions, related collective quantum phenomena and most advanced applications. The monograph is written by the most active authors who have strongly contributed to the advances in this area. It is of great interests to both physicists approaching this subject for the first time, as well as a wide audience of experts in other disciplines who want to be updated on this fast moving field.

Advanced spectroscopic techniques allow the probing of very small systems and very fast phenomena, conditions that can be considered "extreme" at the present status of our experimentation and knowledge. Quantum dots, nanocrystals and single molecules are examples of the former and events on the femtosecond scale examples of the latter. The purpose of this book is to examine the realm of phenomena of such extreme type and the techniques that permit their investigations. Each author has developed a coherent section of the program starting at a somewhat fundamental level and ultimately reaching the frontier of knowledge in the field in a systematic and didactic fashion. The formal lectures are complemented by additional seminars.

Die vierte Auflage der Mechanik wurde in einigen Abschnitten ergänzt (z.B. zur Hamiltonschen Prinzipialfunktion und zum Aufstehkreisel) und auf Fehler durchgesehen, zudem wurden die Aufgaben überarbeitet, wobei nun alle vollständigen Lösungen mit aufgenommen wurden. Das wird all jenen zugute kommen, die diese umfassende Einführung in die Mechanik vorlesungsbegleitend oder zum Selbststudium verwenden wollen. Am Grundaufbau des Buches wurde nichts geändert: von elementarer Newtonscher Mechanik bis zur Diskussion von deterministischem Chaos und kontinuierlichen Systemen. Ein mathematischer Anhang und ein Wegweiser durch die Literatur runden das Buch ab.

In seiner Rede anlässlich der Verleihung des Nobelpreises für Literatur gibt Bob Dylan erstmals umfassend Einblick in seine literarischen Einflüsse und die Ursprünge seines Songwritings. Woher stammen die mythologischen Anspielungen in seinen Texten, woher die manchmal fast biblischen Gleichnisse? Welche Bücher haben seine Einstellung zum Leben geprägt? Und wo hat er die speziellen Ausdrucksweisen, Jargons, Kunstgriffe und Techniken gelernt? Neben dem prägenden Einfluss von Buddy Holly sowie der Country-, Blues- und Folkmusik der späten 50er und frühen 60er Jahre mit ihrer von spezieller Mundart geprägten Lyrics fließen vielfältige literarische Motive in seine Texte ein: die biblische Symbolik in Moby Dick, die Drastik eines Kriegsromans wie Im Westen nichts Neues, aber vor allem das Motiv der Reise aus der Odyssee als universeller, menschlicher Grundverfassung. Aus diesem Bodensatz heraus schuf Bob Dylan, wie er selber sagt, Lyrics, wie sie noch niemand zuvor gehört hatte.
