The technique of stimulated Raman adiabatic passage (STIRAP), which allows efficient and
selective population transfer between quantum states without suffering loss due to …

The motion of neutral molecules in a beam can be manipulated and controlled with
inhomogeneous electric and magnetic fields. Static fields can be used to deflect or focus …

Complex molecular structure demands customized solutions to laser cooling by extending
its general set of principles and practices. Compared with other laser-cooled molecules …

The field of experimental positronium physics has advanced significantly in the last few
decades, with new areas of research driven by the development of techniques for trap** …

We demonstrate direct cooling of gaseous formaldehyde (H 2 CO) to the microkelvin regime.
Our approach, optoelectrical Sisyphus cooling, provides a simple dissipative cooling method …

Stationary molecules in well-defined internal states are of broad interest for physics and
chemistry. In physics, this includes metrology,,, quantum computing, and many-body …

Spectroscopy of hydrogen can be used for a search into physics beyond the Standard
Model. Differences between the absorption spectra of the Lyman and Werner bands of H 2 …

We study rotating quasi-two-dimensional Bose–Einstein condensates, in which atoms are
dressed to a highly excited Rydberg state. This leads to weak effective interactions that …

Producing large samples of slow molecules from thermal-velocity ensembles is a formidable
challenge. Here we employ a centrifugal force to produce a continuous molecular beam with …

Studies of ion–molecule reactions at low temperatures are difficult because stray electric
fields in the reaction volume affect the kinetic energy of charged reaction partners. We …
