Quantum ghosts: atoms become transparent at certain frequencies of light

Collectively induced transparency

Artist’s impression of a laser hitting atoms in an optical cavity. Scientists have discovered a new phenomenon called “collectively induced transparency” (CIT) where groups of atoms stop reflecting light at certain frequencies. The team found this effect by confining ytterbium atoms in an optical cavity and exposing them to laser light. At certain frequencies, a … Read more

Mysterious class of ‘strange metals’ reveals quantum secrets

Quantum Computing Materials

Scientists have made progress in understanding the behavior of a strange metal called Y-ball, which is at the heart of next-generation quantum materials and could drive future technologies. Using gamma rays in a synchrotron and Mossbauer spectroscopy, researchers found unusual fluctuations in Y-ball’s electric charge and discovered that these strange metals could pave the way … Read more
