New quantum simulations suggest carbon hydride (CH) can form a quasi-one-dimensional, spiral superionic state under extreme pressures (500–3,000 GPa) and temperatures (4,000–6,000 K) inside Uranus and Neptune, with hydrogen moving along corkscrew-like paths through a carbon lattice; this directional ion movement could affect heat and electrical transport and help explain the planets’ unusual magnetic fields.
New computer simulations predict a quasi-1D superionic carbon-hydrogen phase inside Uranus and Neptune, where hydrogen atoms navigate spiral pathways through an ordered carbon lattice under 500–3,000 GPa and 4,000–6,000 K, potentially altering heat and electrical transport and helping explain the planets’ unusual magnetic fields.
Scientists predict a quasi-one-dimensional superionic carbon–hydrogen phase under the extreme pressures and temperatures inside Uranus and Neptune, with hydrogen moving along helical pathways within an ordered carbon lattice. This could affect heat and electricity transport, influence magnetic field interpretation, and expand understanding of matter at high pressures relevant to planetary interiors and materials science.
Quantum simulations aided by machine learning uncover a carbon-hydride phase inside Uranus and Neptune in which hydrogen moves along helical channels within a rigid lattice, forming a quasi-1D superionic state that could influence heat, electricity, and the planets’ unusual magnetic fields.
Lab experiments simulating inner-core conditions suggest iron–carbon alloy enters a superionic state, with mobile light atoms softening the solid and slowing seismic waves, potentially explaining long-standing seismic anomalies and offering new insights into Earth's magnetic field generation.
Under pressures above ~40 GPa and temperatures above ~2,200 K, gold forms a solid gold hydride (Au2Hx) with hydrogen diffusing freely in a hexagonal gold lattice in a superionic state. The compound is reversible, reverting to metallic gold when cooled to ambient conditions, and represents the first confirmed binary solid of gold and hydrogen. This discovery challenges gold’s reputation as chemically inert, with implications for high‑pressure physics, planetary interior modeling, and fusion diagnostics, and was observed using a diamond anvil cell and an X-ray free-electron laser.
