    $\begingroup$ I've never seen a column vector like that unless the author was talking about a spinor. $\endgroup$

  • $\begingroup$ I came across something like this in an elementary QM book - $\rvert\psi\rangle$ = \begin{pmatrix} 1/6. e^{ikx-i\omega.t}\\ \sqrt2/6. e^{2ikx-2i\omega.t} \\ \sqrt3/6.e^{3ikx-3i\omega.t} \\ . \\ . \\ .\\ \end{pmatrix} $\endgroup$

  • $\begingroup$ The author writes "...more commonly, however, each component of the state vector represents a function of position and time, something like this - " and then writes the equation I wrote in the comment above. My question is - If the author is wrong then that's the end of the story. If he is correct then is he trying to represent a linear combination of a number of stationary states? $\endgroup$

  • $\begingroup$ Can you specify where you read this? It looks like the writer is trying to make a point... $\endgroup$

    $\begingroup$ note that $|\psi\rangle =\psi(x)|x\rangle$ is wrong. $\endgroup$
