The kick-off of a large-scale European network
for research in 'Thermodynamics in the Quantum Regime' was celebrated
in Brussels on Tues 30 April 2013. The successful proposal for one of the prestigious COST
network grants, funded by the ESF, was led by UCL's researcher Dr Janet Anders.

In a recent STFC newsletter, UK news from CERN, Dr Stephen Hogan describes how he, and a team of international collaborators are investigating the properties of antimatter. The AEGIS experiment at the Antiproton Decelerator, in CERN has been designed to exploit techniques Stephen developed to accelerate antihydrogen atoms in excited states; to transport them and make beams suitable for measurements of the acceleration of antimatter in the Earth's gravitational field.

According to Wannier's law, when a single
photon is absorbed with energy just above the fragmentation threshold, the
electrons in a multi-electron atom break-up in the most symmetric way.

I was an undergraduate and postgraduate at Royal Holloway College, University of London (1954-1960) graduating with a B.Sc in Mathematics in 1957 and a Ph.D in Theoretical Physics in 1961. Having been a Research Assistant at UCL, 1960-1965 and a Research Associate, University of Maryland, 1965-1966, I have been at UCL from 1966 onwards. I have been on the Editorial Board of Journal Physics B: Atomic, Molecular and Optical Physics and am currently Co-Chairman of the working group on line broadening for Commission 14 of the International Astronomical Union (IAU).
My research involves the theoretical study of atomic and molecular processes that occur in low-energy and ultracold physics and in stellar astrophysics. Current research topics include:
- Ultracold collisions between atoms confined in traps
- Low-energy atom-atom collisions and applications to spectral line broadening
- Pressure broadening of spectral lines emitted in intense laser fields
- Polarization of radiation emitted by collisionally excited atoms
- The fundamental three-body problem: two-dimensional R-matrix methods for two-electron atomic systems
This research programme is conducted in collaboration with research groups
in the UK, Australia and France.
