Wavefunctions can be written as weighted sums over Slater determinants and Slater determinants are antisymmetric products of one particle wavefunctions or spin-orbitals. When possible we use $\tau$$\varphi$$$ |\varphi_{\tau}(\vec{r})\rangle = a^{\dagger}_{\tau}|0\rangle $$$\tau\in D$$D_i$$$ |\phi_i\rangle = \Pi_{\tau \in D_i} a^{\dagger}_{\tau}|0\rangle, $$$D_i$$$ \psi = \sum_i \alpha_i \phi_i $$wavefunction index
