Temporal Dynamics of Cycloatoms: Multiple Resonance

Dynamics of multiple resonance

Probability distribution of an initially bound electron in the ground state of hydrogen in the presence of a traveling laser field and a static magnetic field. The static magnetic field is aligned parallel to the magnetic field component of the laser and its frequency is approximately equal to the laser frequency. The figure shows the probability distribution in the x-y plane, where x is the laser polarization direction and y is the propagation direction. The relativistic but classical equations of motion have been solved numerically using a Monte-Carlo method. As time progresses, the probability distribution evolves into a distinct ring-shape.
Computation parameters associated with this movie are as follows. The laser field has a maximum strength of 1 a.u. and an angular frequency of 0.15 a.u. The magnetic field angular frequency is 0.174 a.u. The coulomb potential V(r) = -1 / (r^2+1)^(1/2) was used. The total length of the simulation was 500 optical cycles.
