Ab-initio design of new high-T<sub>c </sub>room-pressure <i>conventional </i>superconductors
Invited
Abstract
In the last five years, ab-initio material design has reshaped the landscape of superconductivity research, leading to an impressive acceleration in new material discoveries. [1]
After room temperature superconductivity was achieved in high-pressure C-S hydride,the next challenge is to identify new strategies to achieve high-tc superconductivity at room pressure.
In this talk, I will propose several strategies, based on the conventional (electron-phonon) mechanism: doping of complex hydrides, new covalent metallic structures of boron and carbon,[3] optimization of binary hydrides.[4]
