The interference of many atoms, and a new approach to boson sampling

In daily life, when two objects are "indistinguishable," it's due to an imperfect state of knowledge. As a street magician scrambles the cups and balls, you could, in principle, keep track of which ball is which as they are passed between the cups. However, at the smallest scales in nature, even the magician cannot tell one ball from another.

Physicists reach atomic-scale telegraphy with light

In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency was named "Hertz" in 1930. Hertz's findings were later used by Guglielmo Marconi (Nobel Prize in Physics, 1909) to transmit information over long distances creating radio communication and revolutionizing wireless telegraphy—shaping the modern world until today.

Attosecond core-level spectroscopy reveals real-time molecular dynamics

Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxation processes known as conical intersections. Such dynamics, which are at the basis of many biological and chemical relevant functions, are extremely difficult to detect experimentally.
