Quantum dots in optical nanocavities are interesting as a test-bed for fundamental studies of light–matter interaction (cavity quantum electrodynamics, QED), as well as an integrated platform for information processing. As a result of the strong field localization inside sub-cubic-wavelength volumes, these dots enable very large emitter–field interaction strengths. In addition to their use in the study of new regimes of cavity QED, they can also be employed to build devices for quantum information processing, such as ultrafast quantum gates, non-classical light sources, and spin–photon interfaces. Beside quantum information systems, many classical information processing devices, such as lasers and modulators, benefit greatly from the enhanced light–matter interaction in such structures. This chapter gives an introduction to quantum dots, photonic crystal resonators, cavity QED, and quantum optics on this platform, as well as possible device applications.

Chapter 11 employs variational differential techniques and the Schwinger Action Principle to derive coupled-field Green’s function equations for a multi-component system, modeled as an interacting electron-hole-phonon system. The coupled Fermion Green’s function equations involve five interactions (electron-electron, hole-hole, electron-hole, electron-phonon, and hole-phonon). Starting with quantum Hamilton equations of motion for the various electron/hole creation/annihilation operators and their nonequilibrium average/expectation values, variational differentiation with respect to particle sources leads to a chain of coupled Green’s function equations involving differing species of Green’s functions. For example, the 1-electron Green’s function equation is coupled to the 2-electron Green’s function (as earlier), also to the 1-electron/1-hole Green’s function, and to the Green’s function for 1-electron propagation influenced by a nontrivial phonon field. Similar remarks apply to the 1-hole Green’s function equation, and all others. Higher order Green’s function equations are derived by further variational differentiation with respect to sources, yielding additional couplings. Chapter 11 also introduces the 1-phonon Green’s function, emphasizing the role of electron coupling in phonon propagation, leading to dynamic, nonlocal electron screening of the phonon spectrum and hybridization of the ion and electron plasmons, a Bohm-Staver phonon mode, and the Kohn anomaly. Furthermore, the single-electron Green’s function with only phonon coupling can be rewritten, as usual, coupled to the 2-electron Green’s function with an effective time-dependent electron-electron interaction potential mediated by the 1-phonon Green’s function, leading to the polaron as an electron propagating jointly with its induced lattice polarization. An alternative formulation of the coupled Green’s function equations for the electron-hole-phonon model is applied in the development of a generalized shielded potential approximation, analysing its inverse dielectric screening response function and associated hybridized collective modes. A brief discussion of the (theoretical) origin of the exciton-plasmon interaction follows.

The methods of coupled quantum field theory, which had great initial success in relativistic elementary particle physics and have subsequently played a major role in the extensive development of non-relativistic quantum many-particle theory and condensed matter physics, are at the core of this book. As an introduction to the subject, this presentation is intended to facilitate delivery of the material in an easily digestible form to students at a relatively early stage of their scientific development, specifically advanced undergraduates (rather than second or third year graduate students), who are mathematically strong physics majors. The mechanism to accomplish this is the early introduction of variational calculus with particle sources and the Schwinger Action Principle, accompanied by Green’s functions, and, in addition, a brief derivation of quantum mechanical ensemble theory introducing statistical thermodynamics. Important achievements of the theory in condensed matter and quantum statistical physics are reviewed in detail to help develop research capability. These include the derivation of coupled field Green’s function equations of motion for a model electron-hole-phonon system, extensive discussions of retarded, thermodynamic and non-equilibrium Green’s functions, and their associated spectral representations and approximation procedures. Phenomenology emerging in these discussions includes quantum plasma dynamic, nonlocal screening, plasmons, polaritons, linear electromagnetic response, excitons, polarons, phonons, magnetic Landau quantization, van der Waals interactions, chemisorption, etc. Considerable attention is also given to low-dimensional and nanostructured systems, including quantum wells, wires, dots and superlattices, as well as materials having exceptional conduction properties such as superconductors, superfluids and graphene.

A growing number of apps and iBooks seek to take advantage of digital technologies to incorporate photos, videos, and audio recordings into editions of Shakespeare’s plays, touting these additions as a boon for understanding Shakespeare. But any promise of transforming how editions can draw on and connect to performances of the plays has not yet been met. Instead, such promises run smack into the limitations of technology, money, rights, and imagination—all hampered by a failure to understand what purpose linking to performances might serve and undermining the pedagogical aims of teaching students to interpret Shakespeare on their own.

Pictures are principally descriptive. Advertising images highlight features of potential purchases; cartoons open portals to scenes in fictional worlds; snapshots in the family photo album remind us of our past selves and landmark events in our personal histories; works of pictorial art express thoughts or feelings about depicted scenes. In addition, pictures serve a directive or action-guiding function that, though not taken into account by theorists, deserves no less attention than their descriptive one. Theories of depiction and the appreciation of pictures stand to benefit by taking ‘directive pictures’ into account, as do theories of representation in general and mental representation in particular.

Abstract This edition updated the material and provides more of an international focus on rabbit production practices around the world. One such change is that units of measure appear in both English (pounds, gallons, feet, etc.) and metric (grams, liters, meters, etc.) systems where numeric measures are given for the convenience of all readers. In addition, the breeds of rabbit photo gallery has been expanded to include breeds from other countries. This edition has also placed more emphasis on the important role of rabbits as a food and income resource in developing countries. This edition also includes an expanded consideration of important issues such as animal welfare and sustainable methods of production. With chapters relating specifically to meat production, pet rabbits, rabbit shows, and angora wool production, this new edition also added new information on the latest methods of artificial insemination, estrous synchronization, embryo transfer, cloning and molecular genetics. It tackles globally prevalent health issues such as enteritis complex (EC) rabbit enterocolitis (REC), and viral hemorrhagic disease. Providing updates on worldwide production trends, figures and new feed additive products, this book is an essential resource for anyone involved in rabbit production - from novice to experienced breeders, veterinarians and industry professionals.

Wrapped in moral judgments about sexual conduct and shrouded in titillating intrigue, legal prostitutes in Nevada’s brothels frequently face oppression and unfair labor practices while managing stigma and isolation associated with their occupational identities. Rooted in organizational communication and feminist theories, this book engages with stories of women living and working in these “hidden” organizations to interrogate issues related to labor rights, stigma, secrecy, privacy, and discrimination in the current legal brothel system. Widespread beliefs about the immorality of selling sexual services have influenced the history and laws of legal brothel prostitution. Moral judgments about legal prostitutes are so pervasive that many women struggle to engage in their communities, conduct business, maintain personal relationships, and transition out of the industry. At the same time, legal brothels operate like other kinds of legal entities, and individuals must contend with balancing work and nonwork commitments, organizational cultures, and managerial relationships. Although legal prostitutes are independent contractors, they often live in their workplaces and must adhere to scheduling requirements, mundane job tasks, and emotional labor, like employees in other organizational settings. Ethnographic observations in the brothels and interviews with current and ex-brothel workers, brothel owners, madams, local police, lobbyists, and others provide a broad data set for analysis. The book includes a photo-elicitation project, featuring images captured by legal prostitutes about their lives in the brothels. Thorough archival research fills in gaps left from inconsistencies, illegal practices, and laws about brothel prostitution. In addition, the third author works as a legal prostitute, providing a deep (and deeply personal) autoethnographic insider look at the industry. As such, this book serves as both an updated resource about the laws and policies which guide legal prostitution in Nevada, and an intimate look at life and decision-making for women performing sex work.

For the past almost fifty years, scientists have been trying to explain the phenomenon of superconductivity. The mechanism is the key ingredient of microscopic theory, which was developed by Bardeen, Cooper, and Schrieffer in 1957. The theory also introduced the basic concepts of pairing, coherence length, energy gap, and so on. Since then, microscopic theory has undergone an intensive development. This book provides a very detailed theoretical treatment of the key mechanisms of superconductivity, including the current state of the art (phonons, magnons, plasmons). In addition, the book contains descriptions of the properties of the key superconducting compounds that are of the most interest for science and applications. For many years, there has been a search for new materials with higher values of the main parameters, such as the critical temperature and critical current. At present, the possibility of observing superconductivity at room temperature has become perfectly realistic. That is why the book is especially concerned with high-Tc systems such as high-Tc oxides, hydrides with record values for critical temperature under high pressure, nanoclusters, and so on. A number of interesting novel superconducting systems have been discovered recently, including topological materials, interface systems, and intercalated graphene. The book contains rigorous derivations based on statistical mechanics and many-body theory. The book also provides qualitative explanations of the main concepts and results. This makes the book accessible and interesting for a broad audience.

Eric Franklin's first edition of Conditioning for Dance was a bestseller—and it is back and better than ever, offering state-of-the-art conditioning exercises for dancers. An internationally renowned master teacher, Franklin has developed a science-based method of conditioning that is taught and practiced in companies and schools around the world. In this new edition of Conditioning for Dance, he integrates the latest scientific research on strength, flexibility, and conditioning into his dance exercises. New to This Edition Since the first edition, the topic of dancers’ health, wellness, and conditioning has taken on even greater importance in the dance community. Franklin has responded to this increased emphasis by adding these new exercises and resources: • Over 100 new conditioning exercises—for all parts of the body—to support dancers in a wide range of genres, forms, and styles • Over 100 new illustrations and photos to explain and show the exercises • Two new chapters with exercises for a complete conditioning plan In addition, the book is now available in full color to enhance image quality in showing technique. Conditioning for Dance now has separate chapters for shoulders and feet, with additional information on calves and ankles. Franklin also offers practical tips to help you develop your personal conditioning plan. Applying Principles Through the Franklin Method Conditioning for Dance uses the principles of resistance training, physics, anatomy, biomechanics, and neuroplasticity (using imagery for positive mental and physical changes) as applied to dance conditioning. Conditioning for Dance blends imagery, focus, and conditioning exercises for dancers to enhance their technique and performance while practicing injury-prevention strategies. Franklin uses experiential anatomy to show and explain how the conditioning principles work to condition your body. As you undertake the exercises, you gain awareness of the body's function and design and take in the knowledge of the principles through movement. This method, known as the Franklin Method, leads to greater understanding of your body, enhanced performance, and fewer injuries. Franklin developed the training systems within the book as well as a line of equipment, including the Franklin Band and Franklin Balls. Franklin has designed the exercises to transfer directly into dance steps; as such, they are appropriate for incorporating into the preparation time for dance classes. Immediate Benefits Conditioning for Dance offers you the culmination of decades of wisdom and experience in dance conditioning from a master teacher. By using its practical exercises, mind–body relationships, and conditioning routines, and in transferring the book knowledge to body experience, you will notice immediate benefits to your conditioning, strength, and flexibility. You will become kinesthetically aware, create great dance technique from within your own body, and begin to craft injury-free and artistically successful routines.

The relationship of the Swiss population to the forest has been investigated in surveys since 1978, and in 1997 for the first time as part of the so-called “Sociocultural forest monitoring” or “Waldmonitoring soziokulturell” WaMos. This report describes the results of the national Wa- Mos3 survey 2020. The online panel of the market research institute LINK was used for the sur- vey. In addition to the representative survey of the adult population, a sample of 156 adolescents was also interviewed. The self-assessed level of information on forest topics has declined since WaMos2 (2010), with older people feeling better informed than younger people. The level of knowledge regarding the increase in forest area in Switzerland and the management of mountain forests for protection against natural hazards is also lower among younger people than among older ones. Today, the population attributes greater importance to most forest functions for society than in WaMos2. In particular, the ecological function, the production function and the recreational function have gained importance. More people than in WaMos2 (2010) assume that forest health has deteriorated. Changes due to climate change, such as drought damage, are perceived by the population. The majority of the population is in favour of active forest management for climate adaptation. With regard to the ecological function of the forest, most people know that biodiversity has decreased. Accor- dingly, the acceptance of forest reserves is high, as is that of large carnivores. Climate change, the expansion of settlements, introduced animal and plant species and pests are seen as the greatest threats to the forest. Great importance is attached to the protective function of the forest. Nevertheless, knowledge about the interrelation between the management and the pro- tective function of mountain forests is declining. In principle, the population is satisfied with the management of the most frequently visited forest. The felling of trees and closing of roads for logging are well accepted by the population. Leaving branches lying on the ground after logging is controversial, and is either well accepted or not accepted at all. Sustainability criteria have gained in importance when purchasing timber products. In terms of forest preferences, the population likes mixed forests best. The presence of a shrub layer is better liked than in WaMos2 (2010) and the liking of deadwood is also increasing at a low level. However, recreational infrastructure is valued less and less. For the first time, forest photos were also presented to the respondents for assessment. It turns out that already existing forest preferences, motives for visiting the forest, the importance of the forest in childhood and the language region have an influence on visual attractiveness of forest. Forest characteristics such as visibility range, shrub layer cover and cover of berry bushes, stage of stand development, stand structure and the presence of deadwood also have an influence. In order to get a picture of which forests people visit, they were asked to mark the forest they visit most often on a map using PPGIS. Local recreation dominates; the densest cloud of points is found where Switzerland is most densely populated. As always, most people go to the forest frequently. The most frequently cited motives for visiting the forest are “experiencing nature”, “enjoying fresh air” and “escaping from everyday life”. Adolescents go to the forest less often. Their activities in the forest are dominated by barbecues/bonfires/parties, jogging and sports in general. Satisfaction with forest visits has decreased at a high level compared to 2010. Forest attractiveness is rated lower, the visit to the forest is perceived as less restorative and the per- ceived disturbances are increasing. In sum, the Swiss population highly values the forest, as a recreational area, but also in particu- lar as a habitat for plants and animals. Ecological awareness seems to have risen again in the last 10 years, and with it concerns about the state of the forest and biodiversity. On the other hand, satisfaction with forest recreation – at a high level – has somewhat declined.
