We evaluate the shifts imparted to vibrational and rotational levels of a linear molecule by a nonresonant laser field at intensities of up to 10(12) W/cm(2). Both types of shift are found to be either positive or negative, depending on the initial rotational state acted upon by the field. An adiabatic field-molecule interaction imparts a rotational energy shift which is negative and exceeds the concomitant positive vibrational shift by a few orders of magnitude. The rovibrational states are…

Laser-induced alignment and anti-alignment of rotationally excited molecules.
The post-pulse alignment of rotationally excited diatomic molecules upon nonresonant interaction with a linearly polarized laser pulse is numerically investigated and a simple model is developed which qualitatively describes the shape and amplitude of post-Pulse alignment induced by a laser pulse of moderate power density.
Ultrafast manipulation of the weakly bound helium dimer
Controlling the interactions between atoms with external fields opened up new branches in physics ranging from strongly correlated atomic systems to ideal Bose1 and Fermi2 gases and Efimov
Coherent control of photoassociation
In this work, the coherence properties of the matter is studied in the frame of photoassociation of ultracold alkali atoms by using short and ultrashort laser pulses. Ultracold can be described with
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
Swirling the weakly bound helium dimer from inside
Controlling the interactions between atoms with external fields opened up new branches in physics ranging from strongly correlated atomic systems to ideal Bose and Fermi gases and Efimov physics.
Libration of Strongly-Oriented Polar Molecules inside a Superfluid.
It is shown that coupling of the molecular pendular motion to the fluctuating bath leads to formation of pendulons-spherical harmonic librators dressed by a field of many-particle excitations, and that an external field allows to fine-tune the positions of these instabilities in the molecular rotational spectrum.
