Quantization of the Radiation Field: Photons

  • Wolfgang Cassing

摘要

In this chapter we describe the quantization of the electromagnetic radiation field, that in quantum mechanics can no longer be described by a classical vector field \(\textbf{A}(\textbf{r};t)\) . Furthermore, we will calculate the interaction between matter and the quantized radiation field in leading order of the coupling.
