Chapter 1: to Quantum Field Theory
This chapter provides an overview of the basic concepts of quantum field theory. It begins with a review of the basics of quantum mechanics, including the Schrödinger equation, the Heisenberg equations of motion, and the postulates of quantum mechanics. It then introduces the concept of a quantum field, which is a quantum-mechanical object that describes the state of a physical system at every point in space and time. The chapter discusses the different types of quantum fields, including scalar fields, vector fields, and spinor fields.
Chapter 2: The Lagrangian and Hamiltonian Formulations
This chapter develops the Lagrangian and Hamiltonian formulations of quantum field theory. The Lagrangian formulation is based on the principle of least action, while the Hamiltonian formulation is based on the principle of conservation of energy. The chapter shows how the two formulations are equivalent and how they can be used to derive the equations of motion for quantum fields.
Chapter 3: The Feynman Path Integral
This chapter introduces the Feynman path integral, which is a powerful tool for calculating the probability of quantum events. The Feynman path integral is a sum over all possible paths that a quantum particle can take between two points in space and time. The chapter shows how the Feynman path integral can be used to derive the Schrödinger equation and the Heisenberg equations of motion.
Chapter 4: The Renormalization Group
This chapter discusses the renormalization group, which is a technique for dealing with the infinite number of divergences that arise in quantum field theory. The renormalization group allows us to calculate the effective values of the coupling constants at different energy scales. The chapter shows how the renormalization group can be used to derive the beta functions, which describe the running of the coupling constants.
Chapter 5: Interactions between Quantum Fields
This chapter discusses the different types of interactions between quantum fields. The chapter begins with a discussion of the electromagnetic interaction, which is mediated by the photon. The chapter then discusses the weak interaction, which is mediated by the W and Z bosons, and the strong interaction, which is mediated by the gluons. The chapter shows how these different interactions can be described using quantum field theory.
Chapter 6: Applications to Quantum Gravity
This chapter discusses the applications of quantum field theory to quantum gravity. The chapter begins with a discussion of the different approaches to quantum gravity, including the canonical approach, the covariant approach, and the loop quantum gravity approach. The chapter then discusses the different problems that need to be solved in Free Download to develop a complete theory of quantum gravity.
