Missing theoretical evidence for conventional room-temperature superconductivity

To elucidate the geometric structure of the putative room-temperature superconductor, carbonaceous sulfur hydride (C-S-H), at high pressure, we present the results of an extensive computational structure search of bulk C-S-H at 250 GPa. Using the minima hopping structure prediction method coupled to the GPU-accelerated sirius library, more than 17 000 local minima with different stoichiometries in large simulation cells …

Has room temperature superconductivity really been achieved?

Our latest work shows that the same theoretical tools that successfully explain other hydride systems under pressure seem to be at odds with the recently claimed conventional room-temperature superconductivity of carbonaceous sulfur hydride (CSH).  Our published article concludes that (1) the absence of a dominant low-enthalpy stoichiometry and crystal structure in the ternary phase diagram. …

Design of electrides: from magnetism to topological phases

In our most recent work is featured as an Editor suggestion’s in Phys Rev. Materials! In this work, we propose a design scheme to explore potential electrides. The searches start with rare-earth-based ternary halides, then we remove the halogen anions and perform global structure optimization to obtain thermodynamically stable or metastable phases with an excess …

Synthesis of a new layered phase predicted by our calculations: a correlated metal?

This is an exciting work we have the opportunity to collaborate with experimental colleagues at the University of Osaka. A new layered perovskite-type oxide Ba2RhO4 was synthesized by a high-pressure technique and predicted by our calculations. The crystal and electronic structure were studied by both experimental and computational tools. Structural refinements for powder x-ray diffraction …
