在朗道的费密液体理论框架下,我们解释了重费密子超导体UBe13的超导临界温度随压力变化的实验结果。所得结论是:PBe13可能是一个P波型的重费密子超导体。同时也发现由于加压使得系统的f能级与费密能级的相对移动和f电子与导带电子杂化的增加对S波超导有利,而对P波超导不利。Applying Landau's Fermi liquid theory, we explain the superconductive critical temperature change with pressure in UBe13. The conclusion is that UBe13 is a possible P-wave superconductor. Furthermore, we find the effect of f energy levels displacement relative to Fermi energy level and s-f hybridization increase due to applying pressure are of benefit to S-wave superconductors, but not of benefit to P-wave superconductor.
