Quantum electrodynamics can be a challenging subject to learn. Fortunately, the tools of mathematics guide us through the process. A recently published textbook, which also constitutes a monograph in later chapters, could help in various challenging contexts.
The field of study has very interesting applications to the high-precision theory of atomic bound states, laser-matter interactions in the relativistic regime, and, on the low-energy side, the description of dynamic processes involving atoms and the quantized electromagnetic field.
