With the publication of its Editorial, we complete a very special JPhysB focus issue in memoriam of British physicist Professor Alexander Dalgarno, who passed away in April 2015.
A guide, friend and/or mentor to the invited authors featured in the collection, Dalgarno is known in the atomic and molecular physics community as the ‘father of molecular astrophysics and ultracold chemistry’.
Guest Editors – James F Babb, Robin Côté, Hossein R Sadeghpour and Phillip C Stancil – have successfully compiled a collection of 16 articles (incl. 2 Letters) spanning the breadth of research close to Dalgarno’s heart, i. e. looking at atomic and molecular processes in the ultracold regime, the chemical regime and astrophysics, giving its name to the focus issue.
We hope you enjoy reading these articles, all currently* free to read, and thank the guest editors and all authors for contributing to this special issue, special on more than one level. (*or for perpetuity when published under an Open Access mandate).
