Title Stripes in Microscopic Theory of High-Tc Superconductivity
Abstract
We examine a realistic 3-band model, finding it capable of exhibiting the d-wave pairing characteristic of CuO2-based high-Tc superconductors, but only in the presence of symmetry-lowering charge-density stripes aligned along (1,0) axes, preferably of diameter 2 cell-widths. The present theoretical treatment has no adjustable parameters (the unit of energy t2/V factors out of both kinetic and potential energy terms,) does not require fine-tuning, and is in qualitative accord with experiment.
