| dc.description | High pressure can strongly influence the electronic properties of a metal, by modifying either the shape or the topology of its Fermi surface (FS). In the case of low-dimensional anisotropic superconductors, typified by high-T<sub>c</sub> cuprates, some quasi-2D organic salts and heavy-fermion compounds, we show that the occurrence of an electronic topological transition is generic to a non-monotonic pressure dependence of the critical temperature T<sub>c</sub>. On the other hand, a change in shape of the FS can be correlated with the steady increase of T<sub>c</sub> as a function of the ratio between next-nearest-and nearest-neighbour hopping, as is observed in the high-T<sub>c</sub> cuprates. |
