Hello all!
I have the following question with regards to quantum mechanics.
If ##H## is a Hilbert space with a countably-infinite orthonormal basis ##\{ \left | n \right \rangle \}_{n \ \in \ \mathbb{N} }##, and two operators ##R## and ##L## on ##H## are defined by their action on the basis elements as follows:
##
\begin{eqnarray}
R \left | n \right \rangle & = & \left | n + 1\right \rangle ,\\
L \left | n \right \rangle & = & \left\{
\begin{array}{11}
\left | n - 1 \right \rangle & \text{for n > 1} \\
0 & \text{for n = 1}.
\end{array} \right.
\end{eqnarray}
##
What are the the eigenvalues and eigenvectors of ##R## and ##L##, if they do exist? Also, what are the hermitian conjugates of ##R## and ##L##?
Thanks in advance!
