Local Electron-Lattice Interactions in High-Temperature Cuprate Superconductors
Figure 1
Oxygen isotope () effect (OIE) exponent α O versus for various families of cuprate HTSs ( denotes the maximum for a particular family). Red circles: ; blue triangles: ; green squares: . The references to the experimental data are given in [16]. The black dashed line is a guide to the eye. The black stars and solid line refer to the calculated when only the nearest neighbour hopping integral is renormalized, whereas the purple stars and solid line refer to the renormalization of , [43–46].
