Spin-dependent Bohm trajectories associated with an electronic transition in hydrogen

The de Broglie–Bohm causal theory of quantum mechanics with spindependence is used to determine electron trajectories when a hydrogen atom is subjected to (semiclassical) radiation. The transition between the 1s ground state and the 2p0 state is examined. It is found that transitions can be identified along Bohm trajectories. The trajectories lie on invariant hyperboloid surfaces of revolution in R3. The energy along the trajectories is also discussed in relation to the hydrogen energy eigenvalues.
