On eigenstates for some $sl_2$ related Hamiltonian
In this paper we consider the stationary Schroedinger equation for a self-conjugated Hamiltonian $H = \frac{e+f}{i}$, where $e$ and $f$ is an anti-unitary pair of the canonical Cartan "creating" and "annihilation" operators for the classical Lie algebra $sl_2$ taken in the representation with "the lowest weight equals to $1$". In this paper we prove that this operator has the continuous spectrum. Construction of eigenstates for $H$ is given in details.
