Fock representation

Informally, a Fock space is the sum of a set of Hilbert spaces representing zero particle states, one particle states, two particle states, and so on. If the identical particles are bosons, the n -particle states are vectors in a symmetrized tensor product of n single-particle Hilbert spaces H. See more The Fock space is an algebraic construction used in quantum mechanics to construct the quantum states space of a variable or unknown number of identical particles from a single particle Hilbert space H. It is named after See more • Fock state • Tensor algebra • Holomorphic Fock space See more A product state of the Fock space is a state of the form which describes a collection of $${\displaystyle n}$$ particles, … See more • Feynman diagrams and Wick products associated with q-Fock space - noncommutative analysis, Edward G.
