Superconductor is the phase without any electrical resistance when they are cooled below a critical temperature. Most of superconducting materials was thought to have to cool to low temperatures, which limited their application. A route to approach high superconductivity is the creation of a metallic hydrogen-rich compound at rather high pressure. Recently, Dr. Hanyu Liu employed a state-of-the-art technique, a heuristic algorithm based on particle swarm optimization CALYPSO, to predict that a pressure-stablized compound of lanthanum and hydrogen (LaH10) would be a near-room-temperature superconductor, which is confirmed by two independent experiment reports sign that the compound is superconducting up to record-breaking -13¡ã and -23¡ã C, which is also room temperature in winter of some cities like Changchun, a big city of North-East China. Besides, Dr. Liu also predicted some unexpected superconducting hydrides like a metastable Li2MgH16 with a unprecedently high critical temperature at high pressure, which was highlighted by some prestigious outlets, such as ScienceNews, and selected for a viewpoint in APS Physics and Editors' suggestion as well as a PRL cover.
