      Anomalous High‐Temperature Superconductivity in YH6 

      Troyan, Ivan A.; Semenok, Dmitrii V.; Kvashnin, Alexander G.; Sadakov, Andrey V.; Sobolevskiy, Oleg A.; Pudalov, Vladimir M.; Ivanova, Anna G.; Prakapenka, Vitali B.; Greenberg, Eran; Gavriliuk, Alexander G.; Lyubutin, Igor S.; Struzhkin, Viktor V.; Bergara Jauregui, Aitor; Errea Lope, Ion ORCID; Bianco, Raffaello; Calandra, Matteo; Mauri, Francesco; Monacelli, Lorenzo; Akashi, Ryosuke; Oganov, Artem R. (Wiley-VCH GmbH, 2021-03-10)
      Pressure‐stabilized hydrides are a new rapidly growing class of high‐temperature superconductors, which is believed to be described within the conventional phonon‐mediated mechanism of coupling. Here, the synthesis of one ...

      Black metal hydrogen above 360 GPa driven by proton quantum fluctuations 

      Monacelli, Lorenzo; Errea Lope, Ion ORCID; Calandra, Matteo; Mauri, Francesco (Nature Physics, 2020-09-07)
      Hydrogen metallization under stable conditions is a major quest for realizing the first room temperature su- perconductor. Recent low-temperature experiments report different metallization pressures, varying from 360GPa ...
