Book description
What happens to light when it is trapped in a box?
Cavity Quantum Electrodynamics addresses a fascinating question in physics: what happens to light, and in particular to its interaction with matter, when it is trapped inside a box? With the aid of a modelbuilding approach, readers discover the answer to this question and come to appreciate its important applications in computing, cryptography, quantum teleportation, and optoelectronics. Instead of taking a traditional approach that requires readers to first master a series of seemingly unconnected mathematical techniques, this book engages the readers' interest and imagination by going straight to the point, introducing the mathematics along the way as needed. Appendices are provided for the additional mathematical theory.
Researchers, scientists, and students of modern physics can refer to Cavity Quantum Electrodynamics and examine the field thoroughly. Several key topics covered that readers cannot find in any other quantum optics book include:
Introduction to the problem of the "vacuum catastrophe" and the cosmological constant
Detailed uptodate account of cavity QED lasers and thresholdless lasing
Examination of cavities with movable walls
Firstprinciples discussion about cavity QED in open cavities
Pedagogical account of microscopic quantization in dielectrics
Complementing the coverage of the most advanced theory and techniques, the author provides context by discussing the historical evolution of the field and its discoveries. In that spirit, "recommended reading," provided in each chapter, leads readers to both contemporary literature as well as key historical papers.
Despite being one of many specialties within physics, cavity quantum electrodynamics serves as a window to many of the fundamental issues of physics. Cavity Quantum Electrodynamics will serve as an excellent resource for advanced undergraduate quantum mechanics courses as well as for graduate students, researchers, and scientists who need a comprehensive introduction to the field.
