Abstract
A parameter-free expression for the superconducting critical temperature of layered cuprates is derived which allows us to express Tc in terms of experimentally measured parameters. It yields Tc values observed in about 30 lanthanum-, yttrium-, and mercury-based samples for different levels of doping. This remarkable agreement with the experiment as well as the unusual critical behavior and the normal-state gap indicate that many cuprates are close to the Bose-Einstein condensation regime.
