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 physics3,4. Such control usually prepares samples that are stationary or evolve adiabatically in time. In contrast, in molecular physics, external ultrashort laser fields are used to create anisotropic potentials that launch ultrafast rotational wave packets and align molecules in free space5. Here we combine…

Pendular alignment and strong chemical binding are induced in helium dimer molecules by intense laser fields
TLDR
A theoretical study of laser interactions in two realms: fields not strong enough to dislodge electrons, but interacts with the anisotropic polarizability to induce spatial alignment of the molecular axis; and superintense, high-frequency lasers that impel electrons to undergo quiver oscillations that interact with the intrinsic Coulomb forces and induce an extremely strong chemical bond.
Imaging the He2 quantum halo state using a free electron laser
TLDR
An extreme quantum system is presented: a gigantic molecule consisting of two helium atoms, with an 80% probability that its two nuclei will be found in this classical forbidden region of space.
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
Probing Weakly-Bound Species with Nonresonant Light: Dissociation of He2Induced by Rotational Hybridization
A field-dependent value of angular momentum can be imparted to a 4 He 2 cluster by the interaction of its anisotropic polarizability with a nonresonant laser field. In this way a centrifugal term is
Fine-tuning molecular energy levels by nonresonant laser pulses.
TLDR
Calculations indicate that 15 and 1.5 ns laser pulses of an intensity in excess of 5 x 10(9) W/cm(2) are capable of dissociating the molecule due to the vibrational shift, which can be used to fine-tune the rovibrational levels and thereby affect collisional resonances by the nonresonant light.

TLDR
The authors show the double-slit interference effect in the strong-field ionization of neon dimers by employing COLTRIMS method to record the momentum distribution of the photoelectrons in the molecular frame.
Probing weakly bound molecules with nonresonant light.
TLDR
Numerical simulations applied to the Rb(2) and KRb Feshbach molecules indicate that shaking by feasible laser pulses can be used to accurately recover the square of the vibrational wave function and, by inversion, also the long-range part of the molecular potential.
