Jan 30, 2025 · The situation is exactly the same in Fock space (also being a Hilbert space). The vacuum state $|0\rangle $ is a properly normalized state with $\langle 0 | 0\rangle=1$.

May 25, 2020 · 4 Fock space is the Hilbert space of multiparticle systems. The difference you're alluding to is a difference of representation. The one you're naturally associating with Fock space is the …

Mar 1, 2021 · The naive definition from your question is demonstrably different: for example, a state that has occupation number 1 for each of the modes belongs to your space but not to the Fock space (as …

The Fock space is an infinite-dimensional (or at least multi-dimensional) harmonic oscillator and it is isomorphic to a tensor product of one-dimensional Fock spaces or harmonic oscillators.

Feb 14, 2025 · From my previous comment, the characteristic function of Fock state is just expectation value of the displacement operator, where the answer is already given in the literature and in this site.

Mar 4, 2024 · These states span the Fock space of a massive scalar boson. starting from the Fock space, it defines an operator (-valued distribution). This operator is a covariant local scalar field, …
