Positron Annihilation Spectroscopy

Understanding material defects at the atomic scale using anitmatter.

Interactions between antimatter and ultracold atoms

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project will investigate how antimatter and matter interact by experimentally studying the interaction of positrons (the electron anti-particle) with trapped ultracold rubidium atoms.

Positron interactions with structured surfaces

We are investigating novel effects and applications using positrons and structured surfaces.
