Since the vacuum has zero momentum we can derive an effective Hamiltonian $H_{eff}$ from $H$ which is only quadratic in the momenta and therefore solvable by standard methods. An approximate ground state wave functional is determined variationally in the limit $η\to 0$.48 pages, 8 figuresHigh Energy Physics - LatticeHigh Energy Physics - Theorytext
