1. Use variational approach with a trial many-body wavefunction in the form of a single Slater determinant to derive the Hartree-Fock equation for the He atom. (100 pts). Hints: a) Write down the many-body Hamiltonian. b) Use Born-Oppenheimer approximation. c) Use atomic unit d) Construct a trial wave-function e) Use variational approach
