    • For instance, in M. Alouani and J. M. Wills, Phys. Rev. B 54, 2480 (1996) it is found that the nonsimultaneous fulfilment of both the f -sum rule and the sum rule satisfied by the imaginary part of the linear dielectric function is an indication of the limitation for the scissors Hamiltonian. Indeed they concluded that the scissors correction well describes the low-lying excited states that include the E1 and E2 bulk critical points, and that the higher excited states are better described by the LDA Hamiltonian alone. However, they used the usual procedure to scissors the linear response. In view of the correct way of including the scissored Hamiltonian, the sum rules for both the linear and the nonlinear response ought to be reconsidered to understand their possible implications in the optical response. 10.1103/PhysRevB.54.2480

    • The crystal class of GaAs, F-43m, gives only one independent component for the susceptibility tensor χabc (-2ω;ω,ω), i.e., χxyz (-2ω;ω,ω) = χzxy (-2ω;ω,ω) = χyzx (-2ω;ω,ω) plus the intrinsic permutation symmetry χabc (-2ω;ω,ω) = χacb (-2ω;ω,ω).
