Oxide Room Temperature Superconductivity At Ambient Pressure: Computations and Experimental Verifications*

Achieving room temperature superconductivity (RTS), at atmospheric pressure in a material of known chemical composition, is regarded as the Holy Grail of condensed matter Physics. Recently, RTS was reported in a carbonaceous sulphur hydride of unknown composition at 2.6 million atmospheres pressure. In our quest to understand superconductivity in oxides, we have developed a Periodic Table based model called MSCD Framework for superconductors. We have used this model to design new high temperature superconductors (HTSCs), as reported in APS March Meetings (2016, 2018). We have also created new design algorithms and architectures that can host HTSCs beyond 160K in oxides, with six to seven elements.
In this presentation, we share these algorithms and architectures. We also formally announce the experimental discovery of new families of oxides with transition temperatures between 273K and 500K at normal atmospheric pressure.
