Quantum Field Theory Approach to Condensed Matter Physics

Introduction

Quantum Field Theory (QFT) is a pivotal framework in understanding complex phenomena in condensed matter physics. My book, "Quantum Field Theory Approach to Condensed Matter Physics," aims to bridge the substantial gap between the elaborate mathematical structure of QFT and the physical understanding required for tackling challenges in condensed matter systems.

Detailed Summary of the Book

In this book, I explore the use of Quantum Field Theory as a fundamental tool to comprehend various phenomena in condensed matter physics. Beginning with an overview of the essentials of QFT, I lay down the necessary groundwork, including the path integral formulation, which serves as the cornerstone of the theoretical framework. The book navigates through the identification and application of field theory in addressing problems related to electron interactions, symmetry breaking, and exotic phases of matter.

The initial chapters focus on classical aspects of field theory, subsequently transitioning into quantum extensions. I meticulously discuss the role of symmetries and conservation laws, which are instrumental in forming effective theories. The book then delves into paradigms like the BCS theory of superconductivity, the quantum Hall effect, and topological insulators, exemplifying how QFT can elucidate the emergence of novel states of matter.

Advanced topics include the renormalization group theory, which offers profound insights into the behavior of systems at critical points, and non-perturbative methods, which are crucial for understanding strong coupling problems. Each chapter is supplemented with problem sets and examples to enhance comprehension and facilitate application to real-world scenarios.
