An international research team led by scientists from City University of Hong Kong (CityU) has recently discovered that high-entropy alloys (HEAs) exhibit exceptional mechanical properties at ultra-low temperatures due to the coexistence of multiple deformation mechanisms. Their discovery may hold the key to design new structural materials for applications at low temperatures.

Eighty-five percent of the universe is composed of dark matter, but we don't know what, exactly, it is.

What is interaction and when does it occur? Intuition suggests that the necessary condition for the interaction of independently created particles is their direct touch or contact through physical force carriers. In quantum mechanics, the result of the interaction is entanglement - the appearance of non-classical correlations in the system. It seems that quantum theory allows entanglement of independent particles without any contact. The fundamental identity of particles of the same kind is responsible for this phenomenon.

Graz University of Technology researchers describe in Physical Review Letters how a molecule moves in the protective environment of a quantum fluid.

Today, when new drugs are designed with the help of supercomputers, and electronic devices operate on a nanoscale, it is very important for scientists to understand how neighboring molecules behave towards each other. For this purpose, they need to know the sizes of atoms with the highest degree of precision.

In a new study published in EPJ D. Tasko Grozdanov from Serbia and Evgeni Solov'ev from Russia describe the configuration and energy levels of antiprotonic helium that can potentially be produced by colliding slow antiprotons with ordinary helium at CERN.
