What is Fock space in Quantum Field Theory and what is its physical interpretation?

Answer 1

Hi vacanucks

A fock space is a mathematical space for the action of QM operators. If you're familiar with operators acting in hilbert spaces, this is like "mutlidimensional" hilbert space - it's the addition of n=0 particle hilbert space (vacuum state), n=1 particle state, n=2, n=3...

I can't think of a physical interpretation for it - I doubt there is one.

Hope this helps!
