  1. The table provides the overlap |〈ψP0|›| and the overlap per site |〈ψP0|›|1/N between the ground state ψP0 of the local Hamiltonian in equation (3) with φ1=0.07 × 2π, φ2=0.03 × 2π, and open boundary conditions and the CFT state in equation (2). is the eigenvalue of the z component of the total spin of ψP0 and , f is the eigenvalue of the operator that flips all the spins, r is the eigenvalue of the operator that rotates the lattice by 180° and D is the dimension of the subspace of Hilbert space that consists of all states with the given eigenvalues. In general, =0, f=(−1)N/2 and r=(−1)N/2 for the CFT state. The overlaps are remarkably high, in particular when taking the large dimension of the involved Hilbert spaces into account.
