Abstract
A new understanding to the origin of superconductivity in hydrogen-rich materials under high pressure is presented in this paper. Applying sufficiently high pressure to a material makes its constituent atoms get close enough so that the “close-shell inversion” effect takes place, which in turn results in superconducting state in the material. Owing to light mass and single proton in their nuclei, under high pressure the hydrogen atoms can be relatively easier squeezed into the neighborhood of heavy ones, facilitating the “close-shell inversion” effect, and in turn realizing superconductivity in the material.
