By Oswald P., Pieranski P.

Nematic and Cholesteric Liquid Crystals is end result of the own learn and of the graduate lectures given via the authors on the Ecole Normale Supérieure de Lyon and the Paris VII collage, respectively. the 1st a part of the booklet offers old history, the trendy type of liquid crystals, and mesogenic anatomy; the second one half examines liquid crystals with nematic and cholesteric orientational order. a number of chapters study defects, floor anchoring transitions, and progress phenomena. The e-book presents an invaluable reference meant for complicated undergraduate and graduate scholars and researchers in liquid crystals, condensed topic physics, and fabrics technological know-how.

Das Riemannsche critical lernen schon die Schüler kennen, die Theorien der reellen und der komplexen Funktionen bauen auf wichtigen Begriffsbildungen und Sätzen Riemanns auf, die Riemannsche Geometrie ist für Einsteins Gravitationstheorie und ihre Erweiterungen unentbehrlich, und in der Zahlentheorie ist die berühmte Riemannsche Vermutung noch immer offen. Riemann und sein um fünf Jahre jüngerer Freund Richard Dedekind sahen sich als Schüler von Gauss und Dirichlet. Um die Mitte des 19. Jahrhunderts leiteten sie den Übergang zur "modernen Mathematik" ein, der eine in research und Geometrie, der andere in der Algebra mit der Hinwendung zu Mengen und Strukturen. Dieses Buch ist der erste Versuch, Riemanns wissenschaftliches Werk unter einem einheitlichen Gesichtspunkt zusammenzufassend darzustellen. Riemann gilt als einer der Philosophen unter den Mathematikern. Er stellte das Denken in Begriffen neben die zuvor vorherrschende algorithmische Auffassung von der Mathematik, welche die Gegenstände der Untersuchung, in Formeln und Figuren, in Termumformungen und regelhaften Konstruktionen als die allein legitimen Methoden sah. David Hilbert hat als Riemanns Grundsatz herausgestellt, die Beweise nicht durch Rechnung, sondern lediglich durch Gedanken zu zwingen. Hermann Weyl sah als das Prinzip Riemanns in Mathematik und Physik, "die Welt als das erkenntnistheoretische Motiv..., die Welt aus ihrem Verhalten im un- endlich kleinen zu verstehen."

In the marginally greater than thirty years in view that its formula, the Hubbard version has turn into a relevant component to glossy many-body physics. It presents a paradigm for strongly correlated, interacting digital structures and gives insights not just into the final underlying mathematical constitution of many-body structures but in addition into the experimental habit of many novel digital fabrics. In condensed subject physics, the Hubbard version represents the best theoret­ ical framework for describing interacting electrons in a crystal lattice. Containing simply specific parameters - the ratio ("Ujt") among the Coulomb repulsion and the kinetic strength of the electrons, and the filling (p) of the to be had digital band - and one implicit parameter - the constitution of the underlying lattice - apparently still in a position to shooting habit starting from metal to insulating and from magnetism to superconductivity. brought initially as a version of magnetism of transition met­ als, the Hubbard version has noticeable a dazzling contemporary renaissance in reference to attainable functions to high-Tc superconductivity, for which specific emphasis has been put on the section diagram of the two-dimensional variation of the version. In mathematical physics, the Hubbard version has additionally had an important position. the answer via Lieb and Wu of the one-dimensional Hubbard version by means of Bethe Ansatz supplied the stimulus for a vast and carrying on with attempt to review "solvable" many-body versions. In better dimensions, there were vital yet remoted distinct effects (e. g. , N agoaka's Theorem).

The prestige of analysis within the Physics of hugely Excited Atoms and Ions is roofed during this monograph. It comprises state-of-the-art techniques and techniques for describing remoted Rydberg atoms and ions, radiative transitions among hugely excited states, and photoionization and photorecombination tactics. The authors current a few effective equipment for the calculations within the thought of collisions of hugely excited atoms and ions with impartial and charged debris and of spectral-line broadening of Rydberg atomic sequence in gases, low- and high-temperature plasmas, and astrophysics. specific consciousness is paid to a comparability of the theoretical effects with to be had experimental data.
