Superconductivity Induced by the Proximity Effect of Singlet Resonating Valence Bond Order in High-$T_c$ Superconductors

M. Hayashi, H. Ebisawa

Effects of inhomogeneous doping on the high-$T_c$ cuprate superconductors are studied within the framework of the t-J model. Especially, the boundary between two non-superconductin…
