  1. Here ✓(✗) means that the DSN susceptibility tensors which contain σL/C and ηL/C defined in Eq. (1) are even (odd) under symmetry operation. Here the even (odd) tensor is allowed (forbidden) by the corresponding symmetry. Note that all DSNs feature the \({{{{{\mathcal{P}}}}}}\)-even characteristic and the DSNs in \({{{{{\mathcal{T}}}}}}\)-invariant systems feature the same behavior with that in \({{{{{\mathcal{P}}}}}}{{{{{\mathcal{T}}}}}}\)-invariant systems.
