Artificial atoms, such as semiconductor quantum dots, exhibit discrete energy levels akin to natural atoms. They offer unique properties due to their nanoscale dimensions and controlled electronic structures. Muonic hydrogen, where a muon replaces the electron, presents an exotic scenario due to the muon's heavier mass and shorter lifetime.
The short lifespan of muons poses challenges for their practical applications, such as in muon-catalyzed fusion. This project aims to investigate the lifetime of muons confined in various semiconductor quantum dots, seeking potential solutions to enhance muon stability and utility.
