Neutron star measurements put limits on color superconductivity in dense quark matter
Ground-based radio telescopes, gravitational wave detectors, and space-based X-ray telescopes (right) all measure neutron stars (top left, showing mergers) and pairings of differently colored quarks in dense matter (bottom left). ). ). Credit: Rachel Steinhorst, NASA/Roscosmos, California Institute of Technology/MIT/LIGO Lab At very high densities, quarks are expected to form pairs, similar to electrons in superconductors. This behavior of dense…

Scientists reveal the secret of superconductivity in iron-based materials
Interfacial structure and vibrational spectrum of superconducting 1 uc FeSe/STO. Credit: Nature (2024). DOI: 10.1038/s41586-024-08118-0 Scientists at the University of California, Irvine have uncovered the atomic-scale mechanics that make iron-based materials superconducting, a discovery recently published in Nature. Using state-of-the-art spectroscopic equipment at the University of California, Irvine Materials Research Institute, the researchers imaged the vibrations of atoms at the…
