28. -1 is multiplied.
29. The single Lorentzian [cf. Eq. (2a)] is the simplest approximation for Im[χ(q, E)] in a low-energy range. We think the quality of fitting using the single Lorentzian shown in Fig. 1(a) is good enough for the present purpose. It should be noted that the double Lorentzian form for Im[χ(q, E)] used in Ref. [18] has been somewhat overemphasized. In fact, the single Lorentzian provides good quality of fitting [Refs. [14,21]; see Fig. 3(c)].
30. We used Eq. (4.2) in Ref. [8], where the factor 3 was replaced by 1, accounting for the strong uniaxial anisotropy.
