A group of three research teams, in which IFISC
(UIB-CSIC) researcher Sungguen Ryu participated, have conducted groundbreaking
experiments demonstrating that high-energy
electrons repel each other upon collision in a beam splitter due to strong
Coulomb interactions. These results clearly show the importance of Coulomb
interaction when manipulating few electron excitations, in contrast to the
photons.
The experiments, published in Nature nanotechnology, fall within the
field of electronic qu...
