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.

What's the best way to calm the butterflies before you speak? Should you open your speech with a joke or a story? What should you do if you forget something important? How do you overcome your fear of speaking to large and small groups? Here, in an easy to access format, you'll find techniques to create and deliver a speech for every occasion, overcome pre-speech nerves, avoid tripping over your tongue, and always look and feel like a Unique and Sexy Speaker. You speak in public every day. Whether you're giving a speech, having a conversation, saying your wedding vows, teaching your kids, exhorting your sales team, or talking in your sleep, if someone is listening, you have the opportunity to influence and to inspire. Being influential and inspirational! That's very sexy!

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. Dan Janal, publicity/marketing/thought leader, and president of PR LEADS. PLUS.com

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
