Experimental Physics with Positronium

Guest Speaker: Dr. Adam Deller, Scientist at Max Planck Institute for Plasma Physics, Garching, Germany
Positronium is a remarkably simple atom. The bound state of an electron and an anti-electron, positronium tends to self-annihilate on the nanosecond time scale. Although short-lived, pulsed lasers can be used to perform spectroscopy, allowing for unique tests of quantum electrodynamics with a purely leptonic system. I will review the current state of experimental physics with positronium and summarize its relevance to atomic, astro, and plasma physics.
