Abstract
Physical properties at ambient condition are only a small fraction of the real figure of materials, and their hidden properties are revealed by pressurization. I and collaborators have studied on physical properties of elements under high pressure using first-principles calculations based on the density functional theory. In this article, I briefly introduce our previous and current works on pressure-induced structural and superconducting transitions in hydrogen, calcium, yttrium, iron, copper, gold, carbon, phosphorus, oxygen, iodine, and argon.
