Quantum-optical spectroscopy on dropletons

摘要

Dropletons are new highly correlated quasiparticles recently discovered in GaAs quantum wells. The dropleton discovery is verified with a new measurement set and the full identification cycle is presented. The analysis confirms that a dropleton contains four or more electron-hole pairs within a tiny correlation bubble and that dropleton's electron-hole pairs are in a liquid-like state that is quantized due to quantum confinement.
