Two-phonon pairing and superconductivity in
Antonio Santacesaria, Cristiano Muzzi, Maria Eleonora Temperini +4
We explore the possibility that the two-phonon pairing mechanism proposed by Ngai can explain superconductivity in doped strontium titanate (STO). The two-phonon deformation potent…

Ternary nickel hydrides: a new platform for unconventional superconductivity and quantum magnetism
Mateusz Domanski, Antonio Santacesaria, Paolo Barone +2
In this letter, we propose ternary nickel hydrides MNiH2 (M = Li, Na) as new materials that mimic cuprate physics but have important differences and interesting properties. Ni-H ba…
