A special form of a quasiclassical approximation in non-relativistic and relativistic quantum mechanics is considered. It consists in the demand of classical interpretation for a natural time of the theory. As the consequence, in passing to quantum level, there arises the necessity of introduction of half-integer spin.

Dynamics of Classical and Quantum Fields: An Introduction focuses on dynamical fields in non-relativistic physics. Written by a physicist for physicists, the book is designed to help readers develop analytical skills related to classical and quantum fields at the non-relativistic level, and think about the concepts and theory through numerous probl
