Eremets’ discovery of high-Tc conventional superconductivity in H3S has profoundly reshaped superconductivity research.[1] In the last decade, superhydrides have pushed the limits of experimental and theoretical imagination, inaugurating a novel paradigm of cooperation between theory and experiment.[2] After superconducting Tc’s exceeding 200 K have been confirmed by different techniques in binary and ternary hydrides, the main challenge is to achieve reproducible control on the synthesis and pressure-quenching of metastable phases. [3] This shift is essential for moving hydride superconductivity toward accessible conditions and, eventually, practical use. In my talk I will highlight what I believe are the most promising directions and the main challenges connected to ab-initio modeling of compounds which should form, survive and operate under strongly non-ideal conditions.
