WebWe will first develop an unrestricted Hartree-Fock (UHF) algorithm using the JK object in Psi4, which is capable of building coulomb-like (J) and exchange-like (K) matrices for arbitrary densities. Then, we will use Psi4 's DFT functional and potential objects to turn the UHF code into a UKS DFT code.
