How complex oscillations in a quantum system simplify with time

Quantum physics allows to make statements about the behavior of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, ...

Better bundled: New principle for generating X-rays

X-rays are usually difficult to direct and guide. X-ray physicists at the University of Göttingen have developed a new method with which the X-rays can be emitted more precisely in one direction. To do this, the scientists ...

A new class of superconductors

A new theory that could explain how unconventional superconductivity arises in a diverse set of compounds might never have happened if physicists Qimiao Si and Emilian Nica had chosen a different name for their 2017 model ...

Adding or subtracting single quanta of sound

Researchers perform experiments that can add or subtract a single quantum of sound—with surprising results when applied to noisy sound fields.

Spreading focus for better imaging

Extreme Ultraviolet (EUV) light in microscopy offers the advantage of obtaining a high-resolution image combined with spectral information about the object under study. However, because EUV microscopy uses diffraction instead ...

Optimal information about the invisible

Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required—and this prerequisite is not always satisfied. In biomedicine, for ...

Researchers guide a single ion through a Bose-Einstein condensate

Transport processes are ubiquitous in nature, but still raise many questions. The research team around Florian Meinert from the Fifth Institute of Physics at the University of Stuttgart has now developed a new method to observe ...
