Scientists 'film' a quantum measurement

Measuring a quantum system causes it to change—one of the strange but fundamental aspects of quantum mechanics. Researchers at Stockholm University have now been able to demonstrate how this change happens. The results ...

Exotic atomic nuclei reveal traces of new form of superfluidity

Recent observations of the internal structure of the rare isotope ruthenium-88 shed new light on the internal structure of atomic nuclei, a breakthrough that could also lead to further insights into how some chemical elements ...

How nature tells us its formulas

Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in solid state ...

Precise measurements find a crack in universal physics

The concept of universal physics is intriguing, as it enables researchers to relate physical phenomena in a variety of systems, irrespective of their varying characteristics and complexities. Ultracold atomic systems are ...

Unexpected twist in a quantum system

Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics.

Attosecond control of an atomic electron cloud

Researchers at SAGA Light Source, the University of Toyama, Hiroshima University and the Institute for Molecular Science have demonstrated a method to control the shape and orientation of an electron cloud in an atom by tuning ...

New method produces robust transistors

A new method to fit together layers of semiconductors as thin as a few nanometers has resulted in not only a scientific discovery but also a new type of transistor for high-power electronic devices. The result, published ...

Laser-based prototype probes cold atom dynamics

By tracking the motions of cold atom clouds, astronomers can learn much about the physical processes which play out in the depths of space. To make these measurements, researchers currently use instruments named 'cold atom ...
