Rotational excitation of molecules in the regime of strong ro-vibrational coupling: Comparison between an optical centrifuge and a transform-limited pulse
J. M. García-Garrido, V. Milner, C. P. Koch +1
We investigate theoretically the ability of an optical centrifuge - a laser pulse whose linear polarization is rotating at an accelerated rate, to control molecular rotation in the…

Rosario González-Férez, Manuel Iñarrea, J. Pablo Salas +1
We investigate the structure and the nonlinear dynamics of two rigid polar rotors coupled through the dipole-dipole interaction in an external homogeneous electric field. In the fi…
Controlling ultracold -wave collisions with non-resonant light: Predictions of an asymptotic model for the generalized scattering volume
Anne Crubellier, Rosario González-Férez, Christiane P. Koch +1
Interactions in a spin-polarized ultracold Fermi gas are governed by -wave collisions and can be characterized by the -wave scattering volume. Control of these collisions by…

The definition of the scattering volume for -wave collisions needs to be generalized in the presence of dipolar interactions for which the potential decreases with the interpart…

Anne Crubellier, Rosario González-Férez, Christiane P. Koch +1
A pair of atoms interacts with non-resonant light via its anisotropic polarizability. This effect can be used to tune the scattering properties of the atoms. Although the light-ato…

Non-resonant light interacting with diatomics via the polarizability anisotropy couples different rotational states and may lead to strong hybridization of the motion. The modifica…
