After Years of Searching, Physicists Observe Electrons Flow Into Whirlpools Like Liquids
For the first time, physicists have witnessed something very interesting: electrons form eddies like liquids. This behavior is one that scientists have long predicted, but never observed before. And that could be the key to developing next-generation electronics that are more efficient and faster. “Electron vortex is expected in theory, but there is no direct evidence yet, and seeing is believing,” said one of the researchers behind the new study, physicist Leonid Levitov of MIT. “Now we’ve seen it, and it’s a clear sign of being in this new regime, where electrons behave as liquids, not as individual particles.” While electrons flowing in a vortex might not sound like a breakthrough, it’s a big deal because flowing like a liquid results in more energy being sent to the end point, instead of being lost on the way while the electrons are pushed around by things like impurities in matter or vibrations in atoms. “We know that when an electron enters a liquid state, [energy] dissipation d
