The first part of the two-piece modern quantum theory textbook is a comprehensive and self-contained introduction to relativistic quantum theory, which leads the reader from the formal structures to archetypal roles theory, the theory of symmetry, quantum spin systems, and motion in external fields. Attached is an introduction to the theory of relativistic electrons in a concept intended for the study of atomic systems.

The text concluded supplements of mathematical apparatus of quantum mechanics written on the edge between "physical" and mathematical precision. Inlaid theory illustrates kvantověmechanický description of a lot of problems with a demonstration of corresponding experiments.

The book is intended for students of master's and doctoral students who are working - either theoretically or experimentally - in atomic systems, and solid state physics. Authors writing benefited from many years of experience in lecturing quantum theory at Charles University in Prague, Masaryk University in Brno, the Academy of Sciences and abroad.

The second part of the textbook is devoted primarily multiparticulates theory of atomic systems.
