Ab-initio Design of superconductors
Over the last ten years, ab-initio methods for superconductivity and crystal structure prediction have seen a substantial advancement, opening the concrete possibility of designing new conventional superconductors completely in silico.[1]
The most spectacular demonstration of the power of this approach is the prediction of high-temperature conventional superconductivity in compressed sulfur hydride [2][3], which started the so-called hydride rush towards room-temperature superconductivity.
However spectacular these discoveries might be, bridging the gap with applications requires devising new strategies to realize high-Tc at more accessible pressures [4][5], and understanding the origin of superconductivity in seemingly simple materials, like Hg and NbTi. [6][7] Finally, I will addressed the challenges that the community needs to address after recent reputation breaches due to false claims of room-temperature superconductivity [8][9].
