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.

WebApr 13, 2016 · Each Fock state has an associated wave function . For example, if a mode is in 0 , then that mode has a Gaussian probability distribution its quadratures. This Guassian wave function is completely different from the spatial profile of the mode ϕ n ( x). Now consider an infinite square well. WebJan 1, 2024 · This is called the occupation-number representation, the n-representation, or Fock space. In the language of second quantization, one does not ask “which particle is in which state,” but rather, “how many particles are there in each state.” The vacuum state, in which all n i = 0, will be abbreviated by (74) O 〉 = 0 1, 0 2 … 0 N 〉.

Fock space and Commutation and anti-commutation relationships, representation of) and the uniqueness theorem: If $ (a _{i} ,\ a _{i} ^{*} ) $ are two Fock representations over $ {\mathcal S} $ with vacuum vectors $ \Omega _{i} $, then they are unitarily equivalent and the unitary equivalence $ U $ is … WebIt is shown that the kernel of the Fock representation of a certain Wick algebra with braided operator of coefficients T, T <= 1, coincides with the largest quadratic Wick ideal. …
Web$\begingroup$ Hi there. I think there is more solid ground on which to justify your first assumptions. I'll write it here and if you like you can edit your answer. In quantum mechanics, a Fock state or number state is a quantum state that is an element of a Fock space with a well-defined number of particles (or quanta). These states are named after the Soviet physicist Vladimir Fock. Fock states play an important role in the second quantization formulation of quantum mechanics. The particle representation was first treated in detail by Paul Dirac for bosons and by Pascual Jord…
