摘要：

The Fock-space Hamiltonian truncation method is developed further, paying particular attention to the treatment of the scalar field zero mode. This is applied to the two-dimensional phi(4) theory in the phase where the Z(2)-symmetry is spontaneously broken, complementing our earlier study of the Z(2)-invariant phase and of the critical point. We also check numerically the weak/strong duality of this theory discussed long ago by Chang.
