Chemists at Ruhr-Universität Bochum have found evidence that carbon atoms cannot only behave like particles but also like waves. This quantum-mechanical property is well-known for light particles such as electrons or hydrogen atoms. However, researchers have only rarely observed the wave-particle duality for heavy atoms, such as carbon. “Our result is one of few examples showing that carbon atoms can display quantum effects,” says Sander. Specifically, carbon atoms can tunnel. They thus overcome an energetic barrier, although they do not actually possess enough energy to do that.
Wolfram Sander explains the paradox: “It’s as though a tiger has ...
