I am a little bit confused about the translation and position operator and hope for some clarification. Let $\hat{x}$ be the position operator, which satisfies $\hat{x} \vert x \rangle = x \vert x \rangle$ and $\hat{T}_{a}$ the translation operator, which satisfies \$\hat{T}_{a} \vert x \rangle =...
