Hybrid ion–atom systems provide an excellent platform for studies of state-resolved quantum chemistry at low temperatures, where quantum effects may be prevalent. Here we study theoretically the process of vibrational relaxation of an initially weakly bound molecular ion due to collisions with the background gas atoms. We show that this inelastic process is governed by the universal long-range part of the interaction potential, which allows for using simplified model potentials applicable to…

Inelastic collision dynamics of a single cold ion immersed in a Bose-Einstein condensate

We investigate inelastic collision dynamics of a single cold ion in a Bose-Einstein condensate. We observe rapid ion-atom-atom three-body recombination leading to formation of weakly bound molecular

Life and death of a cold BaRb+ molecule inside an ultracold cloud of Rb atoms

We study the evolution of a single BaRb$^+$ molecule while it continuously collides with ultracold Rb atoms. The initially weakly-bound molecule can undergo a sequence of elastic, inelastic,

Electric-field dissociation of weakly bound molecular ions

We present a full quantal study on the dissociation of a weakly bound molecular ion in the presence of an external time-dependent electric field. We focus on the dissociation dynamics of a molecular



Vibrational quenching and reactive processes of weakly bound molecular ions colliding with atoms at cold temperatures

We present a study about vibrational quenching and chemical processes of cold molecular ions immersed in an ultracold atomic gas. In particular, the quasiclassical trajectory method is applied to

Explanation of efficient quenching of molecular ion vibrational motion by ultracold atoms

This work theoretically explains the recently observed exception to this rule: efficient vibrational cooling of BaCl+ by a laser-cooled Ca buffer gas, and establishes that there exists a large class of systems that exhibit efficient vibratory cooling and therefore supports a new route to realize the long-sought opportunities offered by molecular structure.

Molecular vibration in cold-collision theory

Cold collisions of ground-state oxygen molecules with helium have been investigated in a wide range of cold-collision energies (from $1\ensuremath{\mu}\mathrm{K}$ up to 10 K) treating the oxygen

Rotational relaxation of molecular ions in a buffer gas

The scattering properties regarding the rotational degrees of freedom of a molecular ion in the presence of a buffer gas of helium are investigated. This study is undertaken within the framework of

Single ion as a three-body reaction center in an ultracold atomic gas.

The final ionic product of the three-body recombination processes is again an atomic Rb(+) ion suggesting that the ion merely acts as a catalyzer, possibly in the formation of deeply bound R b(2) molecules.

Ionic Impurity in a Bose-Einstein Condensate at Submicrokelvin Temperatures.

Detailed line shape analysis of the Rydberg excitation spectrum provides clear evidence for ion-atom interaction at temperatures well below a microkelvin and may open up ways to enter the quantum regime of Ion-atom scattering for the exploration of charged quantum impurities and associated polaron physics.

State-to-state chemistry for three-body recombination in an ultracold rubidium gas

An ultracold few-body quantum state of reactants is prepared and state-to-state chemistry is demonstrated for the recombination of three spin-polarized Ultracold rubidium atoms to form a weakly bound Rb2 molecule.

Ultracold collisions between Li atoms and Li 2 diatoms in high vibrational states

We have performed a quantum-dynamical study of vibrational deexcitation and elastic scattering at ultralow collision energies for the bosonic system {sup 7}Li+{sup 7}Li{sub 2} and for the fermionic

Quantum defect model of a reactive collision at finite temperature

We consider a general problem of inelastic collision of particles interacting with power-law potentials. Using quantum defect theory we derive an analytical formula for the energy-dependent complex

Cold hybrid ion-atom systems

Hybrid systems of laser-cooled trapped ions and ultracold atoms combined in a single experimental setup have recently emerged as a new platform for fundamental research in quantum physics. This paper
