摘要: Abstract We show that the pressure dependence of T c for high- and heavy fermion superconductors can be explained within a generalized electron-hole liquid model called spectator superfluid model. assign structure (e - , B ++ ) hole-doped -- electron-doped superconductors. This classification explains in natural way observed asymmetry. In both cases, experimental gradients are fitted well if component has much smaller effective mass than bosons. The gradient is predicted to smallest near maximum point, agreement with experiments. theory predicts an increase specific heat linear term all four categories. dependences p ( HFS-compounds UBe 13 UPt 3 brought into experiment we (h + them.
