Many-body theory and computation of low-energy antimatter interactions with matter and light
The ability of positrons to annihilate with atomic and molecular electrons forming characteristic gamma rays makes them a unique probe of matter, and gives them important use in medical imaging, astrophysics and materials science. Low-energy positron interactions with atoms and molecules are characterised by strong many-body correlations, including polarization of the electron cloud, screening of the Coulomb interaction, and the unique process of virtual-positronium formation (where a molecular electron temporarily tunnels to the positron). They have an overwhelming effect, causing binding, drastically modifying scattering properties, and enhancing annihilation rates by orders of magnitude.…
