Professor Kun Huang is widely known for his collaboration with Max Born in writing the classic monograph, “Dynamical Theory of Crystal Lattices”. During his years of active research, he has made many important contributions to solid state physics. The present collection of papers is selected at his own choice as representing his most influential works. Thus one finds included his pioneering work on the interaction of radiation field with polar lattices and the resulting coupled vibration modes (later known as “polariton”); the systematic development of his theory of radiative and...
