A (diatomic) shape resonance is a metastable state of a pair of colliding atoms quasi-bound by the centrifugal barrier imposed by the angular momentum involved in the collision. The temporary trapping of the atoms' scattering wavefunction corresponds to an enhanced atom pair density at low interatomic separations. This leads to larger overlap of the wavefunctions involved in a molecule formation process such as photoassociation, rendering the process more efficient. However, for an ensemble of…

Interatomic potentials, electric properties and spectroscopy of the ground and excited states of the Rb2 molecule: ab initio calculations and effect of a non-resonant field*

We formulate the theory for a diatomic molecule in a spatially degenerate electronic state interacting with a non-resonant laser field and investigate its rovibrational structure in the presence of

Pair-eigenstates and mutual alignment of coupled molecular rotors in a magnetic field.

TLDR
The mutual alignment of the pair-eigenstates is evaluated and finds it to be independent of the magnetic field, except for states that undergo avoided crossings, in which case the alignments of the interacting states is interchanged at the magneticField corresponding to the crossing point.

Shaping interactions between polar molecules with far-off-resonant light

We show that dressing polar molecules with a far-off-resonant optical field leads to new types of intermolecular potentials, which undergo a crossover from the inverse power to oscillating behavior
