Electron coherence and pairing correlations in the 2D correlated electron system

Hirokazu Tsunetsugi, Masatoshi Imada

研究成果: Conference article

抜粋

Single-electron spectral function and d-wave pairing correlations are calculated for the 2D t-J model by exact diagonalization including distant single-electron hoppings and three-site pair hoppings. We show that the (π, 0)-level position has a substantial effect on the pairing correlations. It is also suggested that the experimentally observed deep (π, 0)-level is due to the pairing interaction itself. We demonstrate that further enhancement of superconductivity could be achieved by the level tuning through distant hoppings.
