Review:
Author studies, in a clear pedagogical manner, a Hamiltonian H
defined in terms of the two bosonic creation/annihilation
operators in a way inspired by Hradil (ref. [6]). In detail, the
action of H on the specific coherent-state-like states of his/her
previous work is very transparent and supports its rotating-dipole
interpretation in an external electric field. The model proves
solvable in Heisenberg representation giving the zero-point
angular momentum in the evolution equation for angular velocity
and/or angular acceleration. This trivializes the related
Ehrenfest theorems and leads to the correct uncertainty relations
for angular variables.
