Non-Linear Cooperative Effects in Open Quantum Systems


Book Description

This monograph, "Non-linear Cooperative Effects in Open Quantum Systems: Entanglement and Second Order Coherence" is dedicated to the large auditory of specialists interested in the modern approaches in quantum open systems, cooperative phenomena between excited atoms and the field of the non-linear interaction. Special attention is dedicated to the problems of non-linear interaction with vacuum fields and thermostat with finite temperature, but quantum aspects of laser generation of light in non-linear interaction with finite numbers of cavity modes remain the center of attention. In many situations, the limit to the traditional cooperative phenomena of open quantum systems and thermodynamics are taken into consideration. As the book contains the class of non-linear effects of generations of the particle in such cooperative phenomena, the author's aim was to describe squeezed problems and affect entanglement between the generation photons and phonons in cooperative processes. The new phenomenon of cooperative emission in the single- and two-quantum processes are carefully described for large audiences of specialists in the field of quantum optics and condensed matter physics, chemistry and biology.




Cooperative Effects in Matter and Radiation


Book Description

This volume contains the large majority of the papers presented at the Cooperative Effects Meeting which was held as part of the US Army Sponsored Symposium on New Laser Concepts at Redstone Arsenal, Alabama, from November 30 through December 2, 1976. The motivation for the meeting was to bring together a representative cross-section of research scientists active in related areas of cooperative effects in matter-radiation field interaction and coherent pulse generation and propagation. An emphasis was placed upon the rapidly developing areas of superradiance and superf1uorescence, with a balance between theory and experiment in regard to the choice of speakers. This meeting came at a very fortunate time when new experimental results in metal vapors and gases have just recently been realized. Also represented on the programwereareas dealing with new laser concepts such as the free electron laser and two photon amplifier. A few supplemental papers are included in this volume which were authored by participants at the meeting, but were not present on the agenda, primarily due to limited time. These were included because of their relation to the content of papers which were presented and/or were the subject of discussion among attendees. The meeting consisted of eleven invited papers and two work shop sessions, each with a panel. The order of the papers in this volume generally follows the order of their presentation on the agenda. However, the supplemental papers have been inserted where appropriate.




Cooperative Effects in Stochastic Models


Book Description

The monograph is devoted to an investigation of co-operative effects in stochastic models. It includes original results of the authors in the last decade. The main object of the monograph is an analysis of an influence of a stochastic model structure on its characteristics. Problems of a co-operation and a decomposition are actual in a solution of a lot of concrete problems. These problems are: a parallelisation of algorithms and programs, a modelling of supercomputers, computer networks, systems of mobile telephones catastrophes in complex systems, a design and an improvement of technological and economical processes etc. The co-operative effects create a source of significant dependencies between complex system characteristics under large random disturbances. To analyse these effects is necessary to create special methods based on structural analysis of multi-element stochastic models together with majoral asymptotic bounds of these models characteristics. At the same time it demands to develop new approaches to a processing of statistical data and a skill in an usage of the probability theory limit theorems and related asymptotic series and bounds. A choice of the monograph material is defined as by initial applied problems so by probability methods of their solution. Conditionally the monograph may be divided into two parts. First of them contains four sections devoted to a finding of the co-operative effects and to a development of new related analytical and numerical methods. This part has presumably methodological character and creates a theoretical base of an investigation of applied stochastic systems. Second part contains three sections devoted to a solution of different applied problems. It has some interesting substantial results.




Cooperative Effects in Optics, Superradiance and Phase Transitions


Book Description

Cooperative Effects in Optics: Superradiance and Phase Transitions presents a systematic treatment of the modern theory of cooperative optical phenomena-processes in which the behavior of many-body systems of radiators or absorbers is essentially determined by their collective interactions with each other. The book focuses on the theory of collective spontaneous radiation (superradiance) and provides a detailed physical explanation of the mechanism of collective spontaneous emission. It considers numerous models of novel nonequilibrium light-induced phase transitions in a typical quantum electronics system, including two-level atoms interacting with the radiation field and more complex systems of three-level atoms, two-bank semiconductors, and other interatomic interactions with the electrostatic and lattice displacement fields. The book uses some of these models for the interpretation of experimentally observed light-induced critical phenomena. Cooperative Effects in Optics is of great value to research workers in the field of cooperative optical phenomena, especially in the determination of the physical essence of theoretical models developed to describe cooperative effects in multi-atomic systems.

Modes of Cooperative Effects in Dinuclear Complexes


Book Description

This book presents recent advances in dinuclear complexes in which the metal-metal cooperative effect operates for obtaining substrate activation and high performance catalysts. Catalysis continues to be a fast expanding area to design efficient tools in synthesis and in industrial chemistry. It allows performing syntheses with short reaction times, atom economy, reduced consumption of energy and loss of reagents, and low level of wastes. Dinuclear complexes are known to be more efficient than the mononuclear analogues for the reaction rates and the selectivities. This book analyses the latest research, focusing on the key concepts, in building and using these dinuclear complexes. The book is aimed at researchers, graduate students and chemists at all levels in academia and industry.







Cooperative Learning


Book Description

"Gilles focuses the majority of the book on the relationship in the classroom between the individual teacher and the students. She gives teachers ammunition to overcome resistance to cooperative learning by presenting well-substantiated research on virtually every page of her book showing the benefits of having students study together." —Ted Wohlfarth, PSYCCRITIQUES "This text′s greatest strengths are bringing together a range of powerful teaching strategies connected to students taking responsibility for their own learning and the learning of others. The focus on both teacher strategies to encourage effective group talk and student strategies to encourage effective discourse is helpful." —Nancy L. Markowitz, San Jose State University Although cooperative learning is widely endorsed as a pedagogical practice that promotes learning and socialization among students, teachers still struggle with how to introduce it into their classrooms. This text highlights the strategies teachers can use to challenge student thinking and scaffold their learning as well as the strategies students can be taught to promote discourse, problem—solving, and learning during cooperative learning. Key Features Presents cooperative learning in conjunction with national standards: The book situates cooperative learning within the context of No Child Left Behind and a climate of high stakes testing. Links theory with practice: Numerous case studies and small group exercises highlight how teachers can assess both the process and outcomes of cooperative learning. Emphasizes the key role teachers play in establishing cooperative learning: Guidelines are given on how teachers can establish cooperative learning in their classrooms to promote student engagement and learning across various levels and for students of diverse abilities. Incorporates the latest research on cooperative learning: An overview is provided of the major research and theoretical perspectives that underpin the development of cooperative learning pedagogy. Intended Audience This is an excellent supplementary text for several undergraduate and graduate level K—12 teacher preparation and certification courses regularly offered in schools of education. It can also be used as one of several texts in courses on cooperative learning and as a supplement in K—12 teaching methods courses.
