Like the model trains initailly localized wave packets will
move on periodic trajectories like on a track
unstable trajectories and not dispersing on locally stable
While all trajectories are points in a certain
instatenous rotating frame and the WKB wave functions spike
singularly around the turning points of zero velocity
there must be localized eignstates there around
to phase interfere.
The locally rotating frame augmented to the trajectory
tangent circle may be used to study adiabatic stability.
I am looking for various iteresting, for example 8-shaped trajectories
which can support on-average nonspreading Trojan-like wave packets.
Triangle, square and general polygon trajectories are possible
in atoms in combination magnetic and electromagnetic fields for one and more electrons.
Interested in selected exotic eigenstates,
I am currently working on Monte Carlo genetic algorithm implementation
of fixed node method. The nodal constrains are tossed randomly and
than the genetic operations are performed on best nodal populations
to produce better energy estimate of selected excited states and so on.
You can also use it with tossed-node imaginary-time split operator method
