Fock space is a specific type of Hilbert space that is used in quantum mechanics and quantum field theory to describe a variable number of particles. It is constructed as a direct sum of tensor products of single-particle Hilbert spaces, allowing for the mathematical treatment of quantum states with different particle numbers. The structure of Fock space is essential for understanding concepts like cyclic and separating vectors, as it provides the framework for describing states that can be decomposed into simpler components.
congrats on reading the definition of Fock Space. now let's actually learn it.
