Lecture 9: Second Quantization, Fock Space, the Tight Binding Hamiltonian, Two and N Particle Operators, and the Hubbard Model
Travis S. Taylor
In this chapter, we explore the advanced formalism of second quantization, which provides a powerful framework for describing quantum systems with variable particle numbers. We begin with an overview of how operators are second quantized, introducing the essential tools of creation and annihilation operators. These operators form the foundation of Fock space, a versatile representation that accommodates the quantum states of systems with differing particle counts.
