# Metallic hydrogen with a strong electron-phonon interaction at a pressure of 300-500 GPa

## TL;DR

This paper predicts a stable phase of atomic metallic hydrogen with FDDD symmetry under high pressure, highlighting its potential for superconductivity due to strong electron-phonon interactions at 350-500 GPa.

## Contribution

It identifies a stable metallic hydrogen phase with specific symmetry under high pressure, expanding understanding of hydrogen's phases at extreme conditions.

## Key findings

- FDDD symmetry identified as stable structure
- Implication for high-pressure superconductivity

## Abstract

Atomic metallic hydrogen with a lattice with FDDD symmetry is shown to have a stable phase under hydrostatic compression in the range of pressure 350 - 500 GPa.
