Synopsis

Since the prediction of metallic hydrogen in 1936, tremendous efforts have been put into confirming this phase of hydrogen because it holds the promise to be a room temperature superconductor by numerous DFT calculations. This metallic phase of hydrogen is predicted to exist under a tremendous pressure of ~400GPa which is greater than that found at the core of the earth. Recently, a group from Harvard University has claimed for its discovery with a pressure of 495GPa. In this talk, I will provide an overview to the concept of metallic hydrogen, their experiment and results and controversies associated with the experiment.
