Log–log plots of normalized energy, helicity, maximum twist and dipole strength as functions of normalized 1 − P_c for s = 1 (left) and s = 2 (right). In both cases σ = 1. As in Fig. 8, we plot the relative energy and dipole strength and normalize all quantities by their largest values (which for P_c corresponds to its smallest value), listed in Table 4. The vacuum case is retrieved in the limit P_c → 1.
