Question: Prove the commutation relations (11.6.16), assuming that the wave function n (k(vector)) is normalized and symmetric, that is n (k(vector)) = n

Prove the commutation relations (11.6.16), assuming that the wave function ϕ_n(k(vector)) is normalized and symmetric, that is ϕ_n(−k(vector)) = ϕ_n(k(vector)). [CKn, CK.n] =0 [ckckn] - - [Ckck] = $kk - n (K

[CKn, CK.n] =0 [ckckn] - - [Ckck] = $kk - n (K K)n(K k)bk_k k-k = K'n k = - - *(k K)on(k K')b* k b t,k'-k tk-k (11.6.16)
