Two post-doc positions are available to work in my research group on the quantum-mechanical theory of cold and ultracold molecules, to start as soon as convenient. The provisional titles are: 1. Ultracold molecules from ultracold atoms: quantum theory of molecules at nanokelvin temperatures; 2. Cooling molecules to microkelvin temperatures: using the theory of ultracold collisions to cool molecules and understand their behaviour. These positions are for 2 years (with some possibility of extension, depending on how funding develops). They are associated with a large EPSRC grant entitled /MMQA: Microkelvin Molecules in a Quantum Array/, joint with experimental groups at Durham (Eckart Wrede, David Carty, Simon Cornish) and Imperial College London (Ed Hinds, Mike Tarbutt). We also collaborate extensively with experimental groups in Innsbruck, Heidelberg and elsewhere. Cold molecules provide a fascinating playground for molecular quantum mechanics. We develop theory that is closely related to current experiments in this fast-moving field. Applicants will need to have experience in _developing_ theoretical methods in one of the branches of molecular quantum mechanics (collisions, wide-amplitude vibrations, electronic structure, etc. etc.) and will share my fascination with understanding fundamental quantum behaviour in molecular systems. For formal information, or to apply, go to the Durham University Website at https://ig5.i-grasp.com/fe/tpl_durham01.asp and _either_ enter reference number 2262 _or_ search for "Cold Molecules". The closing date for applications is 3 January 2013, and applications _must_ be made via the Web site above (though I am happy to answer informal enquiries by email). For a more informal description of what we do, look at http://www.dur.ac.uk/j.m.hutson/. Further information on the proposed projects (designed for Ph. D. students, but equally applicable to post-docs) is available at http://www.dur.ac.uk/j.m.hutson/studentships-info.pdf . Jeremy Hutson -- Prof. Jeremy M.
