Spectrum of hot methane in astronomical objects using a comprehensive computed line list

A powerful new model to detect life on planets outside of our solar system, more accurately than ever before, has been developed by researchers from UCL Physics & Astronomy and the University of New South Wales. More...

Quantum Phase Transitions

"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.

Quantum mechanics explains efficiency of photosynthesis

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 Gaetana Laricchia

Nella

Born in Barletta (Italy), I was an undergraduate in Physics at UCL from 1980 to 1983 and then a postgraduate obtaining a PhD in positron physics in 1986. From 1986-88 I worked as a postdoctoral research assistant at UCL and Aarhus University in Denmark. In 1988, I was appointed to the UCL staff as a Lecturer. In 1994-1995 I held a Science Research Fellowship awarded by the Nuffield Foundation. I was promoted to Reader in 1996, to Professor in 2003 and appointed Head of the Atomic, Molecular, Optical and Positron Physics group in 2004.

Research interests

My major research interests are in experimental studies of positron and positronium interactions with simple atomic and molecular systems. Particular attention has recently been given to positronium formation and positron impact ionization (including threshold and differential studies), annihilation, the production of positronium beams and positronium scattering. More detail about this research can be found here.
