Structural evolution and superconductivity of thorium under high pressure and its modulation.

The recent revelation of elemental scandium exhibiting a remarkably high superconducting critical temperature () of 36 K under 260 GPa [J. Ying , , 2023, , 256002] has sparked considerable scientific intrigue and attention. In distinction to this exciting study, we focus on the superconductivity of thorium (Th) under high pressure and explore its underlying modulation mechanism.
