Same as Fig.~4 but for $H_1\equiv H_2$. For fields large compared to the soliton mass, $(Z_1+Z_2)H_1\gg M_0$, the entropy approaches the expected analytical value (3.27) for a field theory with two free bosonic sectors and a $SU(3)$ parafermion sector propagating with velocities $v_{\text{quark}}=v_{\text{antiquark}}$ and $v_{pf}$, respectively (full red line). For magnetic fields $zH<M_0$ and temperature $T\ll M_0$ the entropy is that of a dilute gas of non-interacting quasi-particles with degenerate internal degree of freedom due to the $SU(3)_{N_f=2}$ anyons bound to the solitons.
