"Like melting an entire iceberg with a hot poker" – UCL scientists explore the strange world of quantum phase transitions
“What a curious feeling,” says Alice in Lewis Carroll’s tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behaviour we are used to seeing around us is turned on its head.

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis published today in the journal Nature Communications.

Professor Peter Barker
I have a background in atomic and molecular laser spectroscopy, non-linear optics, and laser-induced phenomena in gases. Within the last six years my research has concentrated on the study of molecular manipulation and transport in optical fields. I also have expertise in developing applications from more basic optical physics research. I was awarded a PhD in Physics from the University of Queensland, Australia in 1996. From 1997 to 2001 I was a Postdoctoral Research Associate, and then a Research Scientist and Lecturer in the Applied Physics Group in the Mechanical and Aerospace Engineering Department at Princeton University. At Princeton, I began to study the manipulation of atoms and molecules in pulsed optical fields by studying coherent Rayleigh scattering from molecules trapped in optical lattices. During this time I was part of a multidisciplinary team of physicists and engineers from Princeton University, Sandia National Laboratories and Lawrence Livermore developing a new type of wind tunnel for accelerating gases to hypersonic speeds using lasers and electron beams. In 2001 I took up the position of Lecturer in the Physics Department at Heriot-Watt University and became a Senior Lecturer in 2004. In October 2006 I joined the AMOP group at UCL as a Reader and are currently an EPSRC Advanced Research Fellow. I was promoted to Professor in October 2007 and continue to study the manipulation of molecules in intense optical fields with a particular emphasis on the creation of cold molecules by optical Stark deceleration.
