1. INTRODUCTION Beams of atoms and molecules are stalwart tools for spectroscopy and
studies of collisional processes. 1− 4 The supersonic expansion technique can create cold …

This review summarizes progress in coherent control as well as relevant recent
achievements, highlighting, among several different schemes of coherent control, wave …

This paper presents a review of the current state of the art in the research field of cold and
ultracold molecules. It serves as an introduction to the focus issue ofNew Journal of Physics …

We show how ultracold polar molecules, suggested as a new platform for quantum
computation, can be manipulated to switch “on” and “off” their strong dipole-dipole …

NH radicals are magnetically trapped and their Zeeman relaxation and energy transport
collision cross sections with helium are measured. Continuous buffer-gas loading of the trap …

Ultracold collisions between Cs atoms and Cs 2 dimers in the electronic ground state are
observed in an optically trapped gas of atoms and molecules. The Cs 2 molecules are …

We demonstrate and characterize a cryogenic buffer gas-cooled molecular beam source
capable of producing bright beams of free radicals and refractory species. Details of the …

Over the past decade, and particularly the past five years, a quiet revolution has been
building at the border between atomic physics and experimental quantum chemistry. The …

Employing a two-stage cryogenic buffer gas cell, we produce a cold, hydrodynamically
extracted beam of calcium monohydride molecules with a near effusive velocity distribution …

Alkaline earth monoalkoxide free radicals (MORs) have molecular properties conducive to
direct laser cooling to sub-millikelvin temperatures. Using dispersed laser induced …
