High temperature superconductivity (HTSC) in copper oxides appears upon doping an antiferromagnetic Mott-Hubbard insulator. While at high temperatures the dopants are randomly distributed over the host lattice, at the pseudo-gap temperature T* dynamic patterning in terms of stripe segments is observed. In this regime charge rich and charge poor regions coexist and interact dynamically with each other. It is shown here that this form of heterogeneity leads to multicomponent superconductivity with largely enhanced values of the superconducting transition temperature Tc. The special role played by the lattice is addressed and it is shown that intermediate sized polarons are formed which are the origin of unconventional isotope and strain effects.
