AI Article Synopsis
- - Researchers show that it's possible to control the final states of ultracold molecules when they scatter with atoms by using dynamic magnetic fields at multiple frequencies.
- - A new method called multifrequency Floquet coupled channel method is developed to analyze how these magnetic fields influence which channels are selected during scattering.
- - The study specifically highlights the atom-molecule spin-flip scattering, demonstrating that certain transitions can be suppressed through engineered coupling, reflecting a generalized quantum Zeno effect.
Article Abstract
We demonstrate that final states of ultracold molecules by scattering with atoms can be selectively produced using dynamic magnetic fields of multiple frequencies. We develop a multifrequency Floquet coupled channel method to study the channel selection by dynamic magnetic field control, which can be interpreted by a generalized quantum Zeno effect for the selected scattering channels. In particular, we use an atom-molecule spin-flip scattering to show that the transition to certain final states of the molecules in the inelastic scattering can be suppressed by engineered coupling between the Floquet states.
