The prospect of cooling matter down to temperatures that are close to absolute zero raises
intriguing questions about how chemical reactivity changes under these extreme conditions …

Guided by the above motto (quotation), we review a broad range of issues lying at the
foundations of Density Functional Theory, DFT, a theory which is currently omnipresent in …

Helium is generally understood to be chemically inert and this is due to its extremely stable
closed-shell electronic configuration, zero electron affinity and an unsurpassed ionization …

The prospect of studying state-to-state chemical reaction dynamics, with full control over all
of the reaction parameters, is becoming a reality for a small number of systems. Thanks to …

We review a theory for coupled many-nonlinear oscillator systems that describes quantum
ergodicity and energy flow in molecules. The theory exploits the isomorphism between …

Three-body recombination, or ternary association, is a termolecular reaction in which three
particles collide, forming a bound state between two, whereas the third escapes freely …

Trapped ultracold alkali-metal atoms can be used to measure pressure in the ultra-high-
vacuum and XHV pressure regimes, those with p< 10− 6 Pa. This application for ultracold …

The carbon disulphide (CS 2) dimer is formed inside He nanodroplets and identified using fs
laser-induced Coulomb explosion, by observing the CS 2+ ion recoil velocity. It is then …

In the past two decades, the revolutionary technologies of creating cold and ultracold
molecules have provided cutting-edge experiments for studying the fundamental …

We present a study on ion–atom–atom reaction A+ A+ B+ in a wide range of systems and
collision energies ranging from 100 μK to 10 5 K, analyzing two possible products …
