Quantum Particles Penetrate 5 Barriers

According to new research by Austrian scientists published in the latest edition of the journal Science, quantum particles can tunnel through long-range impassable barriers even though their energy won’t allow for the corresponding trajectory. Known as the quantum tunnel effect, it manifests itself in numerous known phenomena.

For instance, it explains electron transport through quantum dots, fusion reactions inside stars and nuclear radioactive decay. Tunneling is also an essential part of numerous technical processes. For example, it facilitates the imaging of exteriors on the atomic length scale in STMs (scanning tunne...
