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 depending on the intermolecular distance, and whose parameters can be tuned by varying the laser intensity and wavelength. We present analytic expressions for the potential energy surfaces, thereby providing direct access to the parameters of an optical field required to design intermolecular…

Interaction between polar molecules subject to a far-off-resonant optical field: entangled dipoles up- or down-holding each other
We show that the electric dipole–dipole interaction between a pair of polar molecules undergoes an all-out transformation when superimposed by a far-off-resonant optical field. The combined
Manipulation of molecules with electromagnetic fields
The goal of the present article is to review the major developments that have led to the current understanding of molecule–field interactions and experimental methods for manipulating molecules with
Controlling a diatomic shape resonance with non-resonant light
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
Fine structure of open-shell diatomic molecules in combined electric and magnetic fields
We present a theoretical study of the impact of an electric field combined with a magnetic field on the rotational dynamics of open-shell diatomic molecules. Within the rigid rotor approximation, we
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
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.
Quantum phases of quadrupolar Fermi gases in optical lattices.
This work considers a quadrupolar Fermi gas trapped in a 2D square optical lattice, and shows that the peculiar symmetry and broad tunability of the quadrupole-quadrupole interaction results in a rich phase diagram encompassing unconventional BCS and charge density wave phases, and opens up a perspective to create a topological superfluid.
Optical binding with anisotropic particles: resolving the forces and torques
In the phenomenon known as optical binding, optical fields induce significant forces between microparticles of dielectric matter. Most experimental studies have centered on particles of spherical
Quantum control of binary and many-body interactions in ultracold molecular gases
Ultracold molecules are expected to find applications in cold chemistry, quantum phases, precision measurements and quantum information. In this thesis three novel applications of cold molecules are
Entanglement creation in cold molecular gases using strong laser pulses
While many-particle entanglement can be found in natural solids and strongly interacting atomic and molecular gases, generating highly entangled states between weakly interacting particles in a
