Condensation of Hard-Core Pairs on a Lattice: A Model of the Superconducting State in Cuprates
Morten Holm Pedersen, Toni Schneider
Abstract
Using the Monte Carlo technique we study the dependence of transition temperature, penetration depth and specific heat singularity on the pair concentration in the Bose Hubbard model. We observe remarkable agreement with the corresponding properties of cuprates. This points uniquely to Bose condensation of hard-core pairs on a lattice as the mechanism that drives the transition.
