Superconductivity of lutetium polyhydride at megabar high-pressure scale

The research on high-temperature superconductivity （SC） in polyhydrides at an experimentally accessible megabar highpressure scale [1-8] has initiated a growing interest in exploring new high-Tcsuperconductors of polyhydrides.A number of polyhydrides, such as sulfur [1], lanthanum [2], calcium [3,4], zirconium [5], hafnium [6], and tin hydrides [7],have been synthesized, showing superconducting-like properties at megabar pressure.
