Abstract
We have found that the two dimensional (Formula presented) model, for the physical parameter range (Formula presented) reproduces the main experimental qualitative features of high-(Formula presented) copper oxide superconductors: d-wave superconducting correlations are strongly enhanced upon small doping and clear evidence of off-diagonal long-range order is found at the optimal doping (Formula presented) On the other hand, antiferromagnetic long-range order, clearly present at zero hole doping, is suppressed at small hole density with clear absence of antiferromagnetism at (Formula presented). © 2000 The American Physical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
