Free energies of the stable two-scale quasiperiodic structures in the BDL model: the decagonal structure (k5) is the equilibrium phase for T [\lesssim] 1.125 and the dodecagonal structure (k12) is the equilibrium phase for 0.8697 [\lesssim] T [\lesssim] 1.159. Black dots mark the phase transitions, while colored dots mark transitions between linear and nonlinear regimes of the free energy, where the Fourier amplitudes [{\tilde \rho}_1] and [{\tilde \rho}_q] reach a stationary pair of values.
