Scientists report on the detection of particle entanglement in a beam of squeezed light. Researchers were able to observe effects of entanglement monogamy, where particles can be strongly entangled only if they have few entanglement partners.
Taking our understanding of quantum matter to new levels, scientists are exposing high-temperature superconductors to very high magnetic fields, changing the temperature at which the materials become perfectly conducting and revealing unique properties of these substances.
The fact that the neutron is slightly more massive than the proton is the reason why atomic nuclei have exactly those properties that make our world and ultimately our existence possible. Eighty years after the discovery of the neutron, a team of physicists has finally calculated the tiny neutron-proton mass difference. The findings are considered a milestone by many physicists and confirm the theory of the strong interaction.
