Theory of dynamic stripe induced superconductivity

Since the recently reported giant isotope effect on T* (Lanzara A et al 199 9 J. Phys.: Condens, Matter 11 L541 and Rubio Temprano D et al 2000 Phys. R ev. Lett, 84 1990) could be consistently explained within an anharmonic spi n-charge-phonon interaction model, we consider here the role played by stri pe formation on the superconducting properties within the same model. This is a two-component scenario and we recast its basic elements into a BCS eff ective Hamiltonian, We find that the stripe formation is vital to high-T-c superconductivity since it provides the glue between the two components to enhance T-c to the unexpectedly large values observed experimentally.
