Can superconducting rings provide clues to the early development of the universe?
Blast From The Past: Most Distant Stellar Object Gives Clues About Early Universe Astronomers studied the most distant object yet seen in the Universe, a giant stellar blast from more than 13 billion years ago, and learned tantalizing facts about the blast itself and the environment of the star that exploded in the early Universe. • A universal relationship between magnetic resonance and superconducting gap in unconventional superconductors A comprehensive survey of the cuprate, heavy-fermion and iron-based superconductors shows a universal linear relationship between their magnetic resonance energy and superconducting gap. This result suggests that antiferromagnetic fluctuations might play a similar role in the unconventional superconductivity of these seemingly different classes of materials. • Iron-based superconductors: Vital clues from a basic compound Investigation of the phase diagram of the structurally simple compound FeSe may prove instrumental in raising the transition tempe
