and I can't trust it any more " We can generate any multimode Fock state from vacuum state by operating it by Creation operator: (equation) " is wrong,...

Specifically on Hartree-Fock, I think the criteria you suggest, would lead it to be removed from this article. Hartree-Fock of course is, these days...

I have reverted the edit that stated in the edit comment that post-Hartree-Fock methods do not assume the Born-Oppenheimer approximation. First, the statement...

knowledgeable in this area take a look at the article. The sentence "WARNING: Fock space only describes noninteracting quantum fields. See Haag's theorem."...

between a state which is coherent and a "coherent state". A "coherent state" is a specific superposition of fock states (see article). A state that is coherent...

energy of a state by simply adding up the energies of each particle. Thus, the lowest energy state would be the state with no particles: the Fock vacuum....

no signs that "Baron de Robeck" is an officially existing Swedish title. Fock is indeed a baronial (friherre) family. However, it seems that the only reason...

with no information about origins. "Norwegian", "Swedish", "fukka" or "fock" is not mentioned at all. Although I can of course not know if there's been...

electron-density matrix (and fock/kohn-sham matrix, resp.), the cubically scaling diagonalisation step in Hartree-Fock theory and Kohn-Sham density functional...

is passed on by textbooks but that is WRONG, at least as far as Hartree-Fock orbitals are concerned. Virtual orbitals in the HF scheme are a sort of by-product...

would be a useful addition if we specified in more detail what post-hartree-fock methods implemented in the various software. For example, I'm interested...

remark on the link with Fock space? Link or should I say that it is identical? or maybe specialized to Hilbert spaces In physics, Fock spaces describe states...

ground state is the state where all the levels are occupied up to the Fermi level. The Fock-space state corresponding to the ground state is hence something...

the quantum result! If one uses coherent state inputs, coincidence counts due to higher photon number Fock state terms |n>1> of the input states will also...

entities and infinities... Examples of ordinary wavefunctions are functions on Fock spaces that describe the quantum fields that have been observed in our universe...

26 July 2013 (UTC) Michael, so what is the phase of a single photon (Fock state)? — Preceding unsigned comment added by 68.104.252.75 (talk) 17:26, 6...

with edit summary holomorphic Fock space - typo in original ms and User:Dapengzhang0 has just reverted [2] simply stating Undid revision 482167306 by Mathsci...

By the early 1970s, Hartree-Fock orbitals were available for the two states and it became clear that in the triplet state the orbitals are closer to the...

Wavefunctions have no problems with particle creation/annihilation - see Fock state again. --Michael C. Price talk 07:25, 30 June 2008 (UTC) Greeting to all...

rather configurations that are single and double excitations from the Hartree-Fock reference configuration. What do others think? I am happy to make the changes...
