Erratum: Phase transitions of the anisotropic Dicke model (Physical Review A (2023) 107 (043706) DOI: 10.1103/PhysRevA.107.043706)

We find that Fig. 3(e) has been erroneously replaced by the same figure that appears as Fig. 3(h). The correct figure is given below. The text and the conclusions remain unchanged. Figure 3(e) should represent the data for the ground-state multifractal dimension D1 [which one can get by putting q = 1 in Eq. (12) in the paper] of the system Hamiltonian as a function of the spin boson coupling strengths g1 and g2, as in Fig. 3. This figure tells us that the normal-to-superradiant phase transition along the critical line g1 + g2 = 1 is equivalent to the ground state going from a localized to a multifractal phase as we have already discussed in the paper.
