Experiments with Antimatter: Investigating Positron Interactions with Atoms, Molecules and Materials. We will construct a trap-based, positron beam line to be used to investigate the interactions of positrons with matter, namely atoms, molecules, and materials. Specific experimental goals include the observation of positron binding to matter and the investigation of the threshold behaviour of processes such as ionisation by positron impact and positronium formation, where correlation between th ....Experiments with Antimatter: Investigating Positron Interactions with Atoms, Molecules and Materials. We will construct a trap-based, positron beam line to be used to investigate the interactions of positrons with matter, namely atoms, molecules, and materials. Specific experimental goals include the observation of positron binding to matter and the investigation of the threshold behaviour of processes such as ionisation by positron impact and positronium formation, where correlation between the positron and bound electrons plays an important role. The beam line will also provide a unique facility for the investigation and characterisation of new materials.Read moreRead less
Revealing the mechanism of heavy ion stopping at high energies. Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes. In contrast to other studies, the use of crystalline materials with well-defined atom locations and the application of new sop ....Revealing the mechanism of heavy ion stopping at high energies. Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes. In contrast to other studies, the use of crystalline materials with well-defined atom locations and the application of new sophisticated models will allow the separation of these related phenomena, so that they can be studied individually. This will reveal details of the physical mechanisms governing the energy dissipation by fast heavy ions in matter.

Nonlinear atom optics of Bose-Einstein condensates in optical lattices. When a new state of matter - Bose-Einstein condensate - is trapped in a periodic potential created by light, it forms a unique, reconfigurable nano-scale system with unprecedented control over its properties. Its behaviour ranges from quantum to classical, from linear to nonlinear, and from continuous to discrete. This project aims to develop a theory for the nonlinear localization, transport, and excitation of BEC in the op ....Nonlinear atom optics of Bose-Einstein condensates in optical lattices. When a new state of matter - Bose-Einstein condensate - is trapped in a periodic potential created by light, it forms a unique, reconfigurable nano-scale system with unprecedented control over its properties. Its behaviour ranges from quantum to classical, from linear to nonlinear, and from continuous to discrete. This project aims to develop a theory for the nonlinear localization, transport, and excitation of BEC in the optical lattices. Its outcome will provide an important assessment of the feasibility of the proposed use of the BEC in optical lattices in quantum computing, information storage, precision measurements, and nanotechnology.
