A Path Towards Room Temperature Superconductivity? — •Mikhail Eremets — Mikhail Eremets, Max-Planck-Institut fur Chemie, Hahn-Meitner Weg 1, 55128 Mainz, Germany

Room-temperature superconductivity is one of the most challenging and long-standing problems in condensed-matter physics. In 2014, we discovered superconductivity at 203 K in H3S at high pressure, breaking archaic paradigms on conventional superconductivity. Last year, with the advancement of the field, Tc of 250 K was reached in a superhydride LaH10. The mechanism governing these exceptional superconductors is the conventional electron-phonon coupling. Theoretically, predictions point out other compositions that could superconduct at temperatures as high as 470 K. These record-breaking superconductors are the result of chasing of a 50 years old prediction of high-temperature superconductivity in hydrogen. In this respect, we will discuss the most recent efforts on seeking for the superconducting phase of hydrogen. The progress towards room temperature superconductivity is likely to be related first to hydrides under pressure. I will summarize the talk with perspectives for high-temperature conventional superconductivity at moderate and ambient pressure which is expected from arrangements of atoms of light-elements.
