Mathematical devices for optical sciences The Lorentz group which is the underlying scientific language for modern optics has been most notably used for understanding Einsteins special relativity. By using a simplified approach of two by two matrices and Wigner functions this book provides a basic and novel approach to classical and quantum optics making these often difficult subjects more transparent to the reader. Written by three experts in the field Professors Sibel Başkal Young S. Kim and Marilyn E Noz this book will give the reader a comprehensive overview of how fundamental issues in quantum mechanics can be approached using various optical instruments Wigner functions and quantum entanglement.
