| dc.title | Asymptotic model for shape resonance control of diatomics by intense non-resonant light: universality in the single-channel approximation | eng |
| dc.type | Aufsatz | |
| dcterms.abstract | Non-resonant light interacting with diatomics via the polarizability anisotropy couples different
rotational states and may lead to strong hybridization of the motion. The modification of shape
resonances and low-energy scattering states due to this interaction can be fully captured by an
asymptotic model, based on the long-range properties of the scattering (Crubellier et al 2015 New J.
Phys. 17 045020). Remarkably, the properties of the field-dressed shape resonances in this asymptotic
multi-channel description are found to be approximately linear in the field intensity up to fairly large
intensity. This suggests a perturbative single-channel approach to be sufficient to study the control of
such resonances by the non-resonant field. The multi-channel results furthermore indicate the
dependence on field intensity to present, at least approximately, universal characteristics. Here we
combine the nodal line technique to solve the asymptotic Schrödinger equation with perturbation
theory. Comparing our single channel results to those obtained with the full interaction potential, we
find nodal lines depending only on the field-free scattering length of the diatom to yield an
approximate but universal description of the field-dressed molecule, confirming universal behavior. | eng |
