For the nearest-neighbor chain, the finite-size corrections are well-understood from the Bethe Ansatz. In particular, the lowest S=0 is often a “string” excited state, so that the second S=0 excited state is the lowest charge excitation. The gap Δ s − E 0 (S=1) − E 0 (S=0) has higher order corrections which only converge at very large system sizes, but an alternative gap Δ′ s =E 1 (S z =1) − E 0 (S z =1), with E 1 (S z =1) the first spin-particle-hole-excitation, converges more quickly to the L=∞ result (G. Bedürftig, private communication).
