Photon-like electrons in a four-dimensional world discovered in a real material
Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have no mass, and in materials they move with light velocity.
Researchers discover new yttrium-hydrogen compounds with implications for high-pressure superconductivity
Researchers at the University of Bayreuth have made a significant scientific breakthrough by identifying new yttrium-hydrogen compounds, a discovery that has serious implications for research on high-pressure superconductivity. High-pressure superconductivity refers to the property of materials to become superconducting, which means they conduct electrical current without resistance when exposed to certain pressure conditions. The study is published in Science Advances.
