WebNov 21, 2024 · The answer to 1 is yes, but the answer to 2 is (in general) no. (1) is tautological. If Fock states form a basis for Fock space, then by definition any state in that space can be expressed as a linear combination of them. That's just what the definition of the word "basis" means, for any vector space. However, there's a false assumption in the ... WebNov 1, 2024 · We explore the Fock-space structure of eigenstates across the many-body localization (MBL) transition in a disordered, interacting quantum spin- 1 2 chain. Eigenstate expectation values of spatially local observables, which distinguish an MBL phase from an ergodic one, can be represented in terms of eigenstate amplitudes on the …

WebJun 23, 2016 · 1 Answer. Sorted by: 12. It is not a postulate that the Hilbert space for QFT is a Fock space. In fact, for interacting theories is often almost surely not a Fock space. The requirements for a Hilbert space to be the space of a QFT is that the Wightman axioms are satisfied. For free theories, a suitable Fock representation of the canonical ... WebApr 25, 2024 · The Hartree-Fock approximation (HFA) works by assuming each electron sees the effective electric field from all the other electrons as some self-consistent field. The HFA is known to give pretty decent results, but often gets the last quantitative bit of accuracy wrong.
