Vortex beams of atoms and molecules Open
Vortex beams of nonelementary particles The discovery of photon and electron vortex beams carrying orbital angular momentum (as a result of a twisting wave front) has led to appreciable advances in optical imaging, optical and electron mic…

Low-energy collisions between carbon atoms and oxygen molecules in a magnetic trap Open
Trapping of atoms and molecules in electrostatic, magnetic and optical traps has enabled studying atomic and molecular interactions on a timescale of many seconds, allowing observations of ultra-cold collisions and reactions. Here we repor…

Collisions between cold molecules in a superconducting magnetic trap Open
Synopsis 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 molecule-molecule collisions withi…

Trapping of Molecular Oxygen together with Lithium Atoms Open
We demonstrate simultaneous deceleration and trapping of a cold atomic and molecular mixture. This is the first step towards studies of cold atom-molecule collisions at low temperatures as well as application of sympathetic cooling. Both a…

Molecular beam brightening by shock-wave suppression Open
We defeat the fundamental limit on molecular beam flux by cooling interacting surfaces, eliminating disruptive shock waves.
