"Quantum Tunnelling Unveiled Through Flashing Droplets"

Researchers in Sweden and Mexico have discovered that light waves confined in evaporating water droplets can provide a useful model of the quantum behaviour of atoms. The resonance of light inside droplets of specific sizes can provide robust analogies to atomic energy levels and quantum tunnelling. The droplets could boost our understanding of the scattering of light and have practical applications in areas including medicine and environmental monitoring.
