WebApr 10, 2024 · Hartree-Fock calculations scale quadratically with the number of k points. For molecules you only have one of those (if you see them in a Bloch theorem context at all). For solids you have many. This is, why it takes much longer. WebThe general state in a Fock space is a linear combination of product states. A state that cannot be written as a convex sum of product states is called an entangled state . When we speak of one particle in state , we must bear in mind that in quantum mechanics identical particles are indistinguishable.
