Unconventional superconductivity from lattice quantum disorder
The research incorporated nuclear quantum many-body effects into first-principles calculations to find a lattice quantum disordered (LQD) phase in superconductors H3S and La3Ni2O7. This LQD phase occupies a region in the P-T diagram whose boundary matches the superconducting transition temperature (Tc) of the dome's left flank, suggesting this disorder is key to unconventional superconductivity.
