Do mathematicians have a standard name for a pair of orthonormal bases {e_j} and {f_k} of a Hilbert space where |(e_j,f_k)| is independent of j,k? e.g. in C^n, f_k = (1/√n) Σ_{j=1..n} exp(2π j k i/n) e_j Is it “conjugate bases”, as in: https://en.wikipedia.org/wiki/Conjugate_variables …

Amazing! I'm learning slowly and don't want to go down this rabbit hole
