Bose-Einstein condensation of excitons is a unique effect in which the electronic states of a solid can self-organize to acquire quantum phase coherence. The phenomenon is closely linked to Bose-Einstein condensation in other systems such as liquid helium and laser-cooled atomic gases. This is the first book to provide a comprehensive survey of this field, covering theoretical aspects as well as recent experimental work. After setting out the relevant basic physics of excitons, the authors discuss exciton-phonon interactions as well as the behaviour of biexcitons. They cover exciton phase transitions and give particular attention to nonlinear optical effects including the optical Stark effect and chaos in excitonic systems. The thermodynamics of equilibrium, quasi-equilibrium, and nonequilibrium systems are examined in detail. The authors interweave theoretical and experimental results throughout the book, and it will be of great interest to graduate students and researchers in semiconductor and superconductor physics, quantum optics, and atomic physics.

As an international speaker with more than a dozen years of experience speaking to all kinds of audiences, I can say this is a truly useful collection of tips that can help any speaker rise to the next level. I've read many books for speakers, and this is the one I'd use right before I go on stage or as I fly to my next engagement to remind me of the basics and to get a good, positive outlook thanks to its bite-sized chunks of wisdom.

Secrets of a Unique & Sexy Speaker sets out the rules of speaking in clear, concise, and easy-to-follow steps that take the mystery and fear out of public speaking. This is an indispensable guide for anyone who wants to, or has to, stand before an audience to deliver a message. Rona Arato, author of The Last Train, a Holocaust Story
Lucky me! I read Secrets of a Unique & Sexy Speaker before two public appearances, one in front of a hundred or so businesspeople and the other before a board of eighteen. I chose several Speaking Tips to practice and test drive. While much of the book might have you nod in recognition, if you re aware of your own ticks and have received feedback about your speaking, you will as I did benefit enormously from consistently applying these techniques to help you improve. As Marion Claire points out, speaking is a mental as well as physical sport that requires preparation to achieve greater freedom of expression. Thank you, Marion, for your thorough, practical and encouraging guidance. Agnes Mura, MA MCC, global leadership coach, www.AMIcoaches.com
