Ab-initio design of Superconductors: How far is room temperature superconductivity?

The discovery of near-Room-Temperature Superconductivity in High-Pressure Superhydrides has revolutionized the landscape of superconducting material research, establishing ab-initio calculations as the tool of choice for predicting superconducting properties and synthesis conditions of new superconductors. [1]

In this talk, I will give an overview of our recent efforts to design high-Tc conventional superconductors that can operate at ambient pressure[2] and to explore metastable phases of multinary phase diagrams and assess the kinetic stability of promising metastable phases[3]. At the end of the talk, I will briefly address recent claims of room temperature superconductivity at ambient pressure.[4,5]
