Book Description
The optical anisotropy gained by numerous solutions as well as by pure liquids when submitted to the action of an orientating field, is capable of bringing valuable pieces of information on the structure of this field as well as on the physical properties of the particles in solutions. The study of the optical properties arising from this anisotropy only requires the use of a lenearly polarized beam of light on which the medium is going to leave this own characteristics by changing the state of polarization of the light. The flow is created in a conventional Couette cell. It is well known that, in this type of geometry, the hydrodynamical flow undergoes several transistions leading at first to more and more complicated periodical flows, and then, to the turbulence as the angular velocity of the inner rotating cylinder is increased. The aim of this work is to study the behaviour of the properties induced by the flow at the first transition, to work out the theoretical laws controlling this properties and to see in which extend, we can deduce the intrinsec characteristics of the particles. The variation of the extinction angle and of the birefringence intensity is studied at the middle point of the annular gap as a function of the shearing gradient and, for different values of the gradient, as function of the position in the gap. The comparison between the experimental and theoretical curves shows a good agreement in the case of flattened particles (bentonite) but less convincing results for rodlike particles (V.M.T.)

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
