A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common.
Iran says efforts by countries to expand post-sanctions trade ties with it are being hampered by the United States because Washington does not see itself as a beneficiary of the re-opening of the Iranian business environment.
A US coalition of over 60 organizations affiliated with the anti-racism Black Lives Matter movement has released a series of demands, including urging criminal justice reforms and reparations for slavery in the United States.
A team of scientists with the US Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have recorded the first ever observations of rotating topologies of electrical polarization that are similar to the discrete swirls of magnetism known as 'skyrmions'. If these smoothly rotating vortex/anti-vortex topologies prove to be electrical skyrmions, they could find potential applications in ultracompact data storage and processing, and could also lead to the production of new states of matter and associated phenomena in ferroic materials.
