铜氧化物中跳跃感生能量修正的精确性

Finiteness of the Hopping Induced Energy Corrections in Cuprates

Gh. Adam, S. Adam

摘要:

本文继续对有效二维两带哈伯德模型[N. M. Plakida等人,物理评论B,第51卷,16599(1995)]的超导相变的铜酸盐,开始于[Gh. Adam,S. Adam,J. Phys. A:Math.Theor.,Vol.40,11205(2007)]。对该模型的$(δ, T)$相图的讨论指出了在消失掺杂$δ$的极限下能谱的发散。有限的能谱在所有可能的掺杂率$δ$提供的有效哈密顿量的跳跃部分重整化的有效因子指向费米子跳跃过程的网站对的可用性。

英文摘要:

The paper continues the rigorous investigations of the mean field Green function solution of the effective two-dimensional two-band Hubbard model [N. M. Plakida et al., Phys. Rev. B, Vol.51, 16599 (1995)] of the superconducting phase transitions in cuprates, started in [Gh. Adam, S. Adam, J. Phys. A: Math. Theor., Vol.40, 11205 (2007)]. Discussion of the $(δ, T)$ phase diagram of the model points to the divergence of the energy spectrum in the limit of vanishing doping $δ$. Finite energy spectra at all possible doping rates $δ$ are obtained provided the hopping part of the effective Hamiltonian is renormalized with an effective factor pointing to the site-pairs availability for fermion hopping processes.
