• New Models of Jupiter in the Context of Juno and Galileo (2019, background): “On the other hand, at high pressure, hydrogen can form complex polyhydrides molecules very efficiently, with many different atoms (sulfur, lithium, sodium, iron, ...; see e.g. Ashcroft (2004) or Pépin et al. (2017)).”
• Evidence for Superconductivity above 260 K in Lanthanum Superhydride at Megabar Pressures. (2018, background): “Given that the higher hydrogen content in many simple hydride materials is predicted to give still higher T c values [3], we have extended our studies to higher hydrides, the so-called superhydrides, XH n with n > 6.”
• Superconductive sodalite-like clathrate calcium hydride at high pressures (2012, background): “C studies of the hydrides of simple elements at high pressures are motivated by the proposition that a high Tc may be achieved from “precompressed” H2 in dense hydrogen-dominant hydrides (1).”
• Potential high-Tc superconducting lanthanum and yttrium hydrides at high pressure (2017, background): “E his original predictions of very high-temperature superconductivity of high-pressure metallic hydrogen (1), Ashcroft later proposed that hydrogen-rich materials containing main group elements might exhibit superconductivity at lower pressures, as the hydrogen in these structures may be considered ”
• Conventional superconductivity at 190 K at high pressures (2014, background): “These conditions can be fulfilled for metallic hydrogen and covalent hydrogen dominant compounds [4, 5].”
• Solids, liquids, and gases under high pressure (2018, background): “Theories also suggest (Babaev, Sudbø, and Ashcroft, 2004, 2005) that this fluid state, representing a new state of matter, would have unusual properties governed by quantum effects, such as superfluidity and superconductivity.”
• Structure and superconductivity of hydrides at high pressures (2017, background): “group elements to hydrogen [10] and the hydrides with carbon group elements were”
