Dynamics of Classical and Quantum Fields: An Introduction

This text focuses on non-relativistic physics applicable to low-energy situations. Taking a problem-oriented approach, the author develops the theory with the goal of enabling students to formulate and solve problems of their own. Students are encouraged to think about the concepts and theory through numerous problems, helping them develop analytical skills related to classical and quantum fields at the non-relativistic level. In an in-depth yet accessible way, the author presents many topics that would otherwise be intimidating to beginners, such as ＂second＂ quantization path integrals.
