An international
team of researchers around Prof. Ferenc Krausz from the Max Planck
Institute for Quantum Optics in Garching has for the first time
observed electrons in what is known as the "tunnelling process“. The
quantum mechanical tunnelling effect occurs when electrons overcome
the attraction of the atomic nucleus by simply tunnelling through a
potential wall - it is responsible for the ionization of atoms under
the influence of strong magnetic fields. The scientists used new
tools provided by attosecond metrology to show discrete stages of
ionization in this process. "For the first time, our findings
confirmed in real time observation the theoretical predictions of
quantum mechanics," says Ferenc Krausz, Director at the Max Planck
Institute for Quantum Optics and head of the team of
scientists.
