7. Job description:
Our research goal is to realize Positronium (Ps) Bose-Einstein Condensation (BEC). Ps is the bound state of an electron and its antimatter positron. It is the lightest atom. BEC has not been realized yet for systems which contain antimatter. If Ps BEC is obtained, many interesting and important experiments be performed, e.g., antimatter gravity measurement and 511 keV gamma-ray laser development. The challenges are to cool Ps sufficiently and to obtain very high Ps density. New techniques are required and currently under study.
The successful applicant is expected to carry out research to realize Bose-Einstein condensation of positronium focusing mainly on one of the following in cooperation with our collaborators:
- High-density positron beam generation.
- Development of positronium generation, condensation, and cooling nanomaterials.
- Laser cooling of positronium.
* This research will be carried out under the Japan Science and Technology Agency (JST) Fusion Oriented REsearch for disruptive Science and Technology (FOREST) project “Realization of a gamma-ray laser produced from antimatter quantum condensate” (2021—, FOREST Researcher: Dr. Akira Ishida)
