From: Topological incommensurate magnetization plateaus in quasi-periodic quantum spin chains
Finite size effect for magnetization plateaus.
Magnetization plateaus of incommensurate AFM spin-1/2 Heisenberg chains versus the chain length L for systems with δ = 0, λ = 0.8 and different α under PBC. (a) Pα plateau for 
and h = −2.2; (b) Pα plateau for 
and h = −1. Here mDMRG represents magnetization plateau calculated by the DMRG method. The black guidelines denote the corresponding irrational values of magnetization plateaus in thermodynamic limit.
