Abstract
We show that the hole concentration dependence of Tc in YBa2Cu3O6+x- and Nd1+xBa2−xCu3Oy-type superconductors can be understood within a model electron-boson hole liquid that possesses a linear sound mode like the one in liquid He4. The electronic specific heat follows a T3 law near T=0. The metal-insulator transition found in these compounds is proposed to be connected with the vanishing of the sound velocity at small carrier densities.
