Inverse Isotope Effect in the Ternary Perovskite Hydride SrPdH/D${}_{2.9}$: A Signature of Quantum Zero-Point Fluctuations

Wencheng Lu, Mihir Sahoo, Roman Lucrezi +9

Guided by first-principles calculations, we demonstrate superconductivity in the ternary perovskite hydride SrPdH${}_{3-x}$, synthesized at low pressure. Structural characterization…
