  We analyze the calculation of bound states for a nonrelativistic spin-half
neutral particle under the influence of a Coulomb-like potential induced by
Lorentz symmetry breaking effects. We show that the truncation condition
proposed by the authors only provides one energy eigenvalue for a particular
model potential and misses all the other bound-state energies. The dependence
of the cyclotron frequency on the quantum numbers is a mere artifact of the
truncation condition that is by no means necessary for the existence of bound
states.
