Controlling interactions between cold molecules using external fields can elucidate the role of quantum mechanics in molecular collisions. We create a new experimental platform in which ultracold rubidium atoms and cold ammonia molecules are separately trapped by magnetic and electric fields and then combined to study collisions. We observe inelastic processes that are faster than expected from earlier field-free calculations. We use quantum scattering calculations to show that electric fields…

Collisions between cold molecules in a superconducting magnetic trap

We decelerate and trap molecular oxygen using time-dependent magnetic fields and superconducting magnets. The density-dependent, non-exponential decay in particle number provides a clear proof of

Molecular collisions and reactive scattering in external fields: Are field-induced couplings important at short range?

Correct quantum scattering calculations are used to elucidate the role of short-range molecule-field interactions in atom-molecule inelastic collisions and abstraction chemical reactions at low temperatures and highlight the importance of an accurate description of ρ-dependent molecule- field interactions in Quantum scattering calculations on molecular collisions and chemical reactions in low temperatures.

Taming molecular collisions using electric and magnetic fields.

An overview of the various manipulation tools is presented, how they can be used to advantage in molecular beam scattering experiments, and recent progress in this field are reviewed.

Total angular momentum representation for atom-molecule collisions in electric fields

It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed coordinated frame,

Collisions between ultracold atoms and cold molecules in a dual electrostatic-magnetic trap

Measurements of interactions between cold molecules and ultracold atoms can allow for a detailed understanding of fundamental collision processes. These measurements can be done using various

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

Cold heteromolecular dipolar collisions.

The theory presented here represents the first such analysis of collisions between a (2)Π radical and a closed-shell polyatomic molecule and is in agreement with the measured value at zero external electric field.

Molecular collisions: From near-cold to ultra-cold

In the past two decades, the revolutionary technologies of creating cold and ultracold molecules have provided cutting-edge experiments for studying the fundamental phenomena of collision physics. To

Penning collisions between supersonically expanded metastable He atoms and laser-cooled Li atoms.

It is shown that Penning collisions can be directly used to probe the temperature of the Li cloud without the need for an additional time-resolved absorption or fluorescence detection system.

Collisions between Ultracold Molecules and Atoms in a Magnetic Trap.

A single-channel loss model based on quantum defect theory suggests a short-range loss parameter close to unity for rotationally excited molecules, but below 0.04 for molecules in the rotational ground state.
