Uranium chalcogenides; 𝑝-wave electronic superconductor; phonon frequency; Debye temperature; spin fluctuation.

Phonon dispersion relations in uranium chalcogenides have been investigated using a modified three-body force shell model. From the phonon frequencies, their Debye temperatures are evaluated. Further, on the basis of the spin fluctuation in the heavy fermion uranium compounds, UPt₃ and UBe₁₃, the possible superconducting transition temperatures of chalcogenides are theoretically predicted. The 𝑇_c values are in the same range as of those in UPt₃ and UBe₁₃.
