(Nanowerk News) The team led by ETH Zurich Professor Ursula Keller proved three years ago that so-called tunnelling ionization in helium atoms takes place without any appreciable time delay. They have ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

Basic electronic components such as transistors, light-emitting diodes and solar cells made from conjugated polymers are currently investigated for a wide range of applications such as displays, smart ...

Quantum tunnelling, a quintessential quantum mechanical phenomenon, allows particles to penetrate energy barriers that they classically should not overcome. In chemical reactions, this effect is ...

In the world of quantum mechanics, particles can behave like waves. This wave-like nature is crucial for understanding quantum tunnelling. Imagine a tiny particle, like an electron, approaching a hill ...
