Scientists discover new method of observing interactions in nanoscale systems
Abstract:
cientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published recently in the journal Nature.
Researchers conducted experiments with high-powered lasers and quantum dots — artificial atoms that could be the building blocks of nanoscale devices for quantum communication and computing — to learn more about physics at the nanoscale.
One common phenomenon in physics is the Fano effect, which occurs when a discrete quantum state — an atom or a molecule — interacts with a continuum state of the vacuum or the host material surrounding it. The Fano effect changes the way an atom or molecule absorbs light or radiation, said Sasha Govorov, an Ohio University theoretical physicist who is co-author on the paper.
