World-first research at Griffith University is allowing scientists extraordinarily fine time measurements, allowing them to peer into the inner workings of atoms.
Queensland researchers have developed a world-first way to measure time in fantastically tiny intervals, allowing them to peer into the inner workings of atoms.
“Zeptosecond timing is really interesting for us because that is the sort of timescale in which things happen in the nucleus of atoms,” Sang said.A diagram of how the interferometer works.The lasers from the interferometer excite the particles in the heart of the atoms, which then move to a higher energy state and give off a photon.
The specific interferometer the researchers used was unique to Griffith University, Sang said, meaning they were the only institution in the world that could do experiments of this kind at this scale. “Because hydrogen is the simplest molecule in nature and it can be modelled theoretically with high accuracy, it was used in these proof-of-principle experiments for benchmarking and validation of the method,” Litvinyuk said.
