Özet

The recently discovered superconductor LuNi₂B₂C is investigated in the context of strong electron-electron correlations modulated by a squeezed phonon mode propagating in the perpendicular direction to the layers with longitudinal polarization. The squeezed phonons arise in the anharmonic lattice expansion since the linear electron-phonon interaction vanishes due to the structure of the NiB₄ tetrahedra. The observed weak isotope effect and small dependence of T_c on pressure is qualitatively understood within the framework of this model.
