Abstract:
The exactly solvable part of the Heisenberg algebra is found. It is
shown that under the influence of a dynamics that approximates the
Heisenberg dynamics an arbitrary potential in a certain class of
potentials converges as $t\to\infty$ to a first integral of the model, while
the initial state converges to a limit state. The actual dynamics
corresponding to the exactly solvable part of the Heisenberg algebra is calculated exactly.
