We propose a novel general approximation to transform and simplify the description of a complex fully quantized system describing the interacting light and matter. The method has some similarities to the time-dependent Born-Oppenheimer approach: we consider a quantum description of light rather than of nuclei and follow a similar separation procedure. Our approximation allows us to obtain a decoupled system for the light-excited matter and "dressed" light connected parametrically. With these equations at hand, we study how intense light as a quantum state is affected due to the back-action of the interacting matter. We discuss and demonstrate the possibility of the light-mode entanglement and nonclassical light generation during the interaction.

"The interaction of light and matter has long history. It evolved from the ancient corpuscular theory, to wave theory, and finally to the quantum theory. Matter is composed of charged particles, among them positively charged nucleus surrounded by electrons that are in motion. Light is an oscillating electromagnetic wave. But light is also particles (photons). The primary objective of this Field Guide to Light-Matter Interaction is to provide the reader with the basic principles of light and matter interaction using classical, semiclassical, and quantum theories. Within this Field Guide, you will find formulae and descriptions of phenomena that are fundamental for an understanding of the present state of the art of light-matter interaction"--
