Quantum technologies for energy storage and new laser sources

Lead Research Organisation: University College London
Department Name: Physics and Astronomy


The proposed project aims to develop new quantum technologies to realize new energy storage mechanism and new laser sources in the gamma ray range. To this purpose, we will explore collective effects in ultra-cold samples of nuclear isomers. These are caesium atoms with their nuclei in an excited state. The research will involve demonstrating, for the very first time, a Bose-Einstein condensate of nuclear isomers. We will then investigate collective effects, and in particular the possibility of producing coherent gamma emission via collective de-excitation.

Description A paper - linked in the appropriate section - was published about the realisation of a cold atom radio-frequency magnetometer. Following this, a poster was presented at a UCLQ quantum technologies event, and a presentation given for the UCLQ quantum lunch.
Exploitation Route Quantum technologies, specifically quantum enhanced measurements, have many applications. In this case, a cold atom magnetometer may be used for high resolution electromagnetic induction imaging, which could be applied to security and material characterisation.
