The traditional approach transport simulation is to measure cross sections and feed them into a code package. However, some cross sections are very difficult to both measure and calculate. The "inverse swarm problem" seeks to extract these cross sections from transport measruements such as current profiles or annihilation rates.

We create the coldest stuff in the Universe – a Bose-Einstein condensate (BEC) – by laser-cooling helium atoms to within a millionth of a degree Kelvin. At these extremely low temperatures particles behave more like waves. You will use the BEC to study fundamental quantum mechanics and for applications like atom interferometry.

The project aims at establishing the possibilities of high-energy electron scattering in the analysis of thin layers.

This experimental project will characterize the hyperfine fields of ions emerging from target foils as highly charged ions. The data will test theoretical models we are developing, and underpin nuclear magnetism measurements on rare isotopes produced at international radioactive beam facilities such as GANIL (France), ISOLDE-CERN (Switzerland) and NSCL (USA).

The emission rate of low-energy Auger electrons and X-rays from radiosotopes through the Auger cascade are extremely important for basic science and applications, especially for medical isotopes. The project is aiming to understand the nature of the Auger cascade and develop a new computational model for the research of targeted radioisotopes therapy.

An optical quantum memory will capture a pulse of light, store it and then controllably release it. This has to be done without ever knowing what you have stored, because a measurement will collapse the quantum state. We are exploring a "photon echo" process to achieve this goal.

Auger electrons are emitted after nuclear decay and are used for medical purposes. The number of Auger electrons generated per nuclear decay is not known accurately, a fact that hinders medical applications. This project aims to obtain a experimental estimate of the number of Auger electrons emitted per nuclear decay.

Positron emitters are embedded in clouds of dust grains produced by supernova. This project will explore the transport of positrons in dust grains using Monte-Carlo techniques to improve our understanding of positron transport in an astrophysically relevant setting.

Characterising plasmas is difficult. This project will explore the possibilty of probing a plasma using positrons by building a model and simulating a positron beam incident on a low-temperature plasma.

Motivated by exciting prospects for measurements of the magnetism of rare isotopes produced by the new radioactive beam accelerators internationally, this computational project seeks to understand the enormous magnetic fields produced at the nucleus of highly charged ions by their atomic electron configuration.

A novel approach to low energy electron experiments has been developed, using strong magnetic fields to confine the electron beam. This project will further develop a new apparatus towards making important measurements of scattering cross sections.

This is a multi-faceted project which can be adapted to students at the honours level and above. A number of possibilities exist to perform experiments directed towards improving the use of positrons in medice, mostly focussed on Positron Emission Tomography (PET).
